Reported congressional-hearing preparation with human counsel
A human preparation process supplies the current-work example. The AI preparation packet below is a separate proposal, not a reported deployment or proof of a successful hearing.
Prepare executives for congressional hearings
WilmerHale practice described by Alyssa DaCunha
Practitioner-reported manual preparation process, published 12 November 2026; no AI deployment or measured outcome established.
A published third-party example, not a Nuvepro customer case or evidence of a partnership.
The workflow at a glance
Briefings, mock hearings and stakeholder preparation
Illustrative summary of the published account
Reported work components. Their arrangement does not imply a fixed execution order or simultaneous work.
- Counsel and witness
Tailor factual briefings
Lawyers assess what the witness knows. They explain missing facts or help a knowledgeable witness give clear, concise answers.
- Lawyers and witness
Rehearse timed questioning
After briefings, lawyers play committee members in mock hearings with timed rounds and anticipated questions.
- Counsel and client
Prepare testimony and surrounding communications
The account describes considering testimony, media outreach, board briefings and employee communications while preparing the witness.
- Human witness
Practice delivery in a challenging forum
Preparation covers interruptions, respectful delivery and explaining complex material in a short answer.
What the source reports
In David Lat’s interview, Alyssa DaCunha describes assessing witnesses’ knowledge, tailoring briefings and then running timed mock hearings with lawyers playing committee members. Communications and internal stakeholder preparation surround that work. Counsel advises; witnesses make their own decisions. This is a reported professional process, not an inspected client matter.
Reported technology: Human legal team; no AI preparation deployment reported. Scope and outcomes are source-reported.
What the enterprise environment would need
The following is a proposed project design for an enterprise doing similar work. Published details are marked; the remaining systems, data and scenarios would be agreed for your project.
Proposed practice environment
Prepare a source-linked hearing rehearsal packet
Illustrative project design to scope with your enterprise.
- 1 · Set up the environment
Fictional matter and counsel-approved facts
Use dated synthetic records, a counsel-approved fact index, access and privilege labels, a witness learning profile and a scoped public committee brief. Counsel defines what may enter the exercise.
- 2 · Preparation and agent contributions
AI drafts an issue map and mock questions
An agent links factual topics and rehearsal prompts to permitted records, identifies contradictions and leaves unknowns unresolved. Counsel and the witness prepare answers; the agent must not invent witness knowledge or testimony.
- 3 · Independent checks
Independent counsel checks the packet
A separate reviewer compares every factual reference with the approved record set, checks dates, withheld material and access, and rejects unsupported assertions. Mock-question coverage is checked against a counsel-authored reference.
- 4 · People decide acceptance
Lead counsel accepts the exact packet
The responsible lawyer resolves open issues and accepts or rejects the independently checked packet version for the scoped rehearsal. The witness retains responsibility for truthful testimony; this acceptance is not legal clearance or readiness proof.
A reviewable evidence package
A versioned preparation packet with source-linked facts, mock questions, unresolved issues, independent review results and counsel disposition.
If a check fails → withhold acceptance.
A conflicting fact, stale record, restricted source or counsel rejection blocks acceptance. Repair or remove the affected material, rerun independent checks against current approved records, and return the revised packet to lead counsel.
Failure or owner rejection returns to review
- Hold
- → 2 · Revise work
- → 3 · Rerun independent checks
- → 4 · Owner review
Operating boundary. Designed checks, not executed. Synthetic, counsel-scoped practice only. No legal advice, invented testimony, privileged live records, automatic external communications or filing. Domain counsel must confirm scope and expected answers.
- Fictional hearing records and counsel scope
- Proposed: counsel prepares a fictional corporate record set, approved issue list, document dates and access boundaries in an isolated workspace. Establish the reference facts and missing evidence before an agent runs.
- AI assistance and lawyer preparation
- Proposed: an agent drafts a source-linked issue and fact index with mock question prompts. Lawyers resolve conflicts, write or edit preparation materials and conduct rehearsal; the agent must not invent witness knowledge or testimony.
- Independent record and access checks
- Proposed: a separate counsel reviewer checks every factual assertion and citation against the frozen reference set, including dates, unresolved contradictions and permitted access. A generated answer cannot verify itself.
- Lead counsel acceptance and witness authority
- Proposed: lead counsel accepts the exact independently checked preparation packet or returns it for repair, independent rechecks and renewed review. Witnesses retain testimony decisions. No filing, external communication or live hearing action is enabled.
A proposed simulation
An illustrative practice design derived from this work, not an executed assessment.
Proposed: assemble a cited preparation packet and mock question prompts from fictional counsel-approved hearing records, retaining uncertainty and lawyer control.
Review gate: Lead counsel accepts only the exact packet whose facts, citations, dates and access passed independent review. Acceptance does not establish witness readiness, authorize testimony or permit external communication.
Challenge the result: A cited record changes after review and contradicts the packet. Withdraw acceptance, surface the conflict, repair the affected material and repeat independent checks before lead counsel reviews it again.
What needs checking
- Source boundary: the published interview describes human preparation. AI transcript editing by the publisher is not AI-enabled witness preparation, and no client outcome was independently observed.
- Proposed: test a well-informed witness, an executive missing key facts, conflicting dated records and an unsupported question premise against counsel-authored reference facts. Flag missing support rather than fabricate an answer. Designed, not executed.
- Proposed: change a cited record or introduce restricted material after review. Withhold acceptance, repair the packet and repeat independent citation/access checks before lead counsel reviews the new version. Designed, not executed.
Review environment fidelity, human capability and agent performance separately. The enterprise’s accountable owners decide acceptance of the shared workflow and any operating use.
How an enterprise could build similar work
A proposed build order for an enterprise doing similar work, written by Nuvepro from the published account and our interpretation of the environment and checks above. It is not how WilmerHale practice described by Alyssa DaCunha built or operates this work.
- Agree fictional records and accessProposed: counsel freezes the reference records, issue list, document dates and access limits.
- Draft a cited preparation packetProposed: an agent maps facts and uncertainties to sources and drafts mock question prompts; lawyers resolve conflicts and prepare the witness.
- Independently verify the packetProposed: a separate counsel reviewer checks factual support, dates, citations and permitted access against approved references.
- Repair unsupported or stale materialProposed: reject unsupported assertions or changed records, repair the packet and repeat independent checks.
- Lead counsel reviews the exact versionProposed: lead counsel accepts or returns the checked packet. No filing, contact or testimony authority follows from practice acceptance.
Your systems, data, rules and accountable owners decide the real project. Agree acceptance criteria, escalation owners and operating responsibility with the people accountable for the work before anything runs on live records. Treat the first run as a rehearsal on test records: compare the draft output with an independently prepared answer, and record what the people reviewing it change.
Questions about this example
- Does this source describe AI-enabled witness preparation?
- No. It is a practitioner account of human preparation. The AI workspace on this page is proposed separately.
- How strong is the source evidence?
- The publisher-edited interview transcript was not reviewed by the interviewee. No client records, measured outcome or audio replay were used for this review.
- Can the proposed agent write testimony or contact a committee?
- It may draft a source-linked preparation index and mock questions for counsel review. It cannot invent witness facts, file material or send communications; the witness retains testimony decisions.
- Have the proposed checks been executed?
- No. They are designed checks for a fictional practice environment. Counsel must approve domain rules before implementation.
Shape this around your enterprise
Bring a similar workflow and the people responsible for it. Together, define the records and systems to use, the result your team will build or configure, and how its owners will check it. Nuvepro scopes the simulation, environment and preparation. Agree any existing-agent evaluation, implementation assistance and production responsibilities separately.
Sources and limitations
Curation review: . This is the date this source example was reviewed, separate from source publication dates.
- The publisher cleaned up the transcript and says the interviewee did not review it. This review used the public text; the audio was not played.
- The account supplies no inspected client preparation packet, independent outcome measurement or deployed AI witness-preparation system.
- This process summary is not legal advice. Political forecasts and hearing-success claims are outside its scope.
- The proposed AI workspace, controls and checks are fictional and unexecuted. Counsel must confirm the domain rules; a checked packet does not prove witness readiness or authorize production use.
