Overview

Mark Paoletta is an American attorney who has served as a senior legal official in both of Donald Trump’s administrations. He served as General Counsel of the Office of Management and Budget (OMB) from January 8, 2018, to January 20, 2021, and returned to OMB as Chief Counsel in January 2025. Before joining OMB in the first term, he served as Chief Counsel and Assistant to Vice President Mike Pence (January 2017–January 2018) and spent a decade as Chief Counsel for Oversight and Investigations on the U.S. House Committee on Energy and Commerce.

Paoletta is the principal legal architect of the Trump administration’s theory of executive impoundment power — the claim that the President has authority to withhold congressionally appropriated funds at will, reversing settled post-Watergate law under the Impoundment Control Act of 1974. In January 2025, he authored the OMB memo that ordered all federal agencies to pause grant and loan disbursements. That memo triggered widespread legal challenges and has been partially blocked by federal courts. He is also the attorney who drafted the legal justification for withholding congressionally appropriated military aid to Ukraine in 2019 — one of the central acts underlying Trump’s first impeachment.

• Basis for inclusion: Role as OMB Chief Counsel and primary legal architect of the administration’s impoundment theory; authored the January 2025 spending pause memo; authored the 2019-2020 legal justification for the Ukraine aid hold that was the basis for Trump’s first impeachment inquiry; documented role in restructuring how executive agencies exercise spending discretion
• What is NOT the basis: Political views, party affiliation, or conservative legal philosophy in general
• Speech characterization: Legal memoranda and arguments documented in this profile were produced in official government capacities; they are official government conduct, not protected private speech

Background

Paoletta spent approximately a decade as Chief Counsel for Oversight and Investigations for the House Committee on Energy and Commerce, where he worked on congressional investigations and oversight matters. He joined the Trump administration in January 2017 as Chief Counsel and Assistant to Vice President Mike Pence. In January 2018, he moved to OMB as General Counsel, serving in that role through the end of Trump’s first term on January 20, 2021.

After leaving government, Paoletta maintained a public profile as a conservative legal commentator and writer defending impoundment authority. He published arguments asserting that the President retains constitutional authority to withhold funds even after the Impoundment Control Act, a position that mainstream legal scholars and prior administrations across both parties have disputed.

He returned to OMB as Chief Counsel in January 2025.

Ukraine Aid Hold — First Term (2019–2020)

In the summer of 2019, the Trump administration placed a hold on approximately $391 million in congressionally appropriated military security assistance to Ukraine. Paoletta, as OMB General Counsel, wrote a legal memorandum asserting that the hold was lawful — that the administration had authority to temporarily pause the funds while conducting a policy review.

The hold became the central subject of Trump’s first impeachment inquiry. The Government Accountability Office (GAO) issued a legal opinion on January 16, 2020, finding that OMB had violated the Impoundment Control Act by withholding the Ukraine security assistance.

The GAO, a nonpartisan legislative branch watchdog, concluded: “Faithful execution of the law does not permit the President to substitute his own policy priorities for those that Congress has enacted into law.”

Paoletta publicly disputed the GAO’s conclusion and argued the administration’s position was legally correct.

January 2025 Spending Pause Memo

On January 27, 2025 — one week after the second inauguration — OMB issued a memo, written by Paoletta, ordering all federal agencies to “temporarily pause all activities related to obligation or disbursement of all Federal financial assistance” pending a review of whether programs aligned with Trump’s executive orders.

The memo prompted immediate legal challenges. Federal courts issued emergency orders blocking the freeze within days. The memo was withdrawn on January 29, 2025, but administration officials stated the underlying policy review would continue through other means.

Accountability Concerns

• Impoundment Control Act violations: The GAO found OMB violated the ICA in 2020 over the Ukraine hold. In 2025, courts repeatedly blocked Paoletta-authored spending freeze directives as likely violations of the ICA and the Administrative Procedure Act.
• Scope of claimed executive spending power: Paoletta has publicly argued for an expansive executive impoundment power that would effectively subordinate congressional appropriations to presidential policy preferences — a position that legal scholars across the political spectrum have called constitutionally unsupported.
• Documented pattern: Two administrations, two significant legal findings (GAO 2020; court injunctions 2025) that OMB actions Paoletta was involved in violated federal law.
