• IDF uniform worn on Capitol Hill – dual loyalty concerns for Foreign Affairs chairman 505 days silent
  Expected position: As the newly elected chairman of the House Foreign Affairs Committee, Mast would be expected to address concerns raised by members of his own party and detractors about wearing an Israeli military uniform in the Capitol building, which a GOP primary challenger called 'traitorous' and which critics argue compromises his ability to conduct impartial foreign policy oversight. Evidence of activity on adjacent topics: Mast wore his IDF uniform to the Capitol on October 13, 2023, days after the Hamas attack. When asked about it, he deflected with a comment about Rep. Rashida Tlaib. His GOP primary challenger in 2024 called him a 'traitor.' Mast subsequently leaned into the controversy, tweeting in 2026 that he was 'proud to be the only member of Congress who has worn both the uniform of the United States Army and the uniform of the Israel Defense Forces.' During the months after becoming HFAC chairman, he has not addressed how this dual-loyalty perception might affect his committee's work on Middle East policy.

• STOCK Act violation – late disclosure of Virgin Galactic stock while sitting on aviation oversight subcommittee 397 days silent
  Expected position: As a member of the House Transportation and Infrastructure Subcommittee on Aviation with oversight authority over aerospace companies, Mast would be expected to address his failure to disclose up to $100,000 in Virgin Galactic stock within the legally required 45-day window — a purchase made weeks after Virgin Galactic's president testified before his subcommittee. Evidence of activity on adjacent topics: Mast missed the deadline to disclose the Virgin Galactic stock purchase. When Business Insider broke the story on August 16, 2022 documenting the violation alongside Sen. Rick Scott, Mast did not return a request for comment. He was active on social media and in committee hearings throughout this period. Florida Politics also reported that Mast's office 'did not immediately respond to a request for comment' regarding the STOCK Act questions.

• H.Con.Res. 14 / H.R. 1 ↗ YEA 2025-07-03
  One Big Beautiful Bill Act — Permanent extension of 2017 tax cuts; $4.5 trillion in tax reductions weighted toward upper-income earners; expanded SNAP work requirements to age 64
  why contradicted?

  [against_constituent] Only 2 of 218 House Republicans voted against the bill. Mast celebrated it as delivering 'permanent tax relief' and benefits 'for children, seniors, veterans, and small businesses.' Independent analyses project 17 million Americans losing health coverage and SNAP work requirements pushing seniors into food insecurity — directly affecting FL-21's large retiree population.
• H.R. 8404 ↗ YEA THEN NAY 2022-12-08
  Respect for Marriage Act — Federal protection for same-sex and interracial marriages; repeals the 1996 Defense of Marriage Act
  why contradicted?

  [reversal] Mast voted yes in July 2022, then flipped to no on final passage in December. He was one of only 7 Republicans to reverse, aligning with social conservative pressure. The reversal was unexplained and occurred in a district that includes urbanizing areas of Palm Beach County.
• H.R. 3684 ↗ NAY 2021-11-05
  Infrastructure Investment and Jobs Act — $1.2 trillion for roads, bridges, broadband, water, and transit
  why contradicted?

  [reversal] Mast voted against the bipartisan infrastructure law while separately requesting $725 million for Everglades restoration and later criticizing the administration for not allocating enough Everglades money from the bill he opposed. Florida received approximately $1.1 billion in Everglades funding from this legislation.
• H.R. 2 ↗ YEA 2018-05-18
  Agriculture Improvement Act of 2018 (Farm Bill) — Introduced stricter SNAP work requirements, projected to cut $20 billion from food assistance over a decade
  why contradicted?

  [against_constituent] Mast voted for stricter SNAP work requirements in a district with 10.7% poverty and 7.1% unemployment. Constituents expressed concern at the time. Mast defended the vote saying he believes in being 'smarter stewards of taxpayer dollars.'
• H.R. 1628 ↗ YEA 2017-05-04
  American Health Care Act of 2017 — Partial ACA repeal; CBO projected 23 million more uninsured; allowed state waivers for pre-existing condition protections
  why contradicted?

  [against_constituent] Mast's district has a 10.7% poverty rate and a median age of 48.2 with 27.1% of residents over 65 — a population disproportionately dependent on ACA protections. Mast receives his own healthcare through the VA, leading constituents to accuse him of being insulated from the bill's consequences.

No documented broken promises on file.

• statement_vs_disclosure SCORE 90
  Mast publicly claimed to protect people with pre-existing conditions while voting for the AHCA, which the CBO projected would cause 23 million to lose coverage and which permitted states to waive essential health benefits including pre-existing condition protections. He receives his own healthcare through the VA, insulating him from the law's effects.
• reversal SCORE 90
  Mast voted yes on the Respect for Marriage Act in July 2022 then flipped to no on final passage in December 2022. The reversal aligned with pressure from social conservative groups after the initial vote drew criticism from the right. No public explanation was provided for the reversal.
• statement_vs_disclosure SCORE 90
  Mast voted against the infrastructure bill as a 'socialist wishlist' but then publicly demanded that the Biden administration allocate Everglades restoration funding from the very same bill — a project he previously said needed $725 million in federal infrastructure investment. He took credit for pushing the Army Corps to fund the project after voting against the funding mechanism.
• statement_vs_disclosure SCORE 60
  Mast, who sits on the Aviation Subcommittee that oversees commercial spaceflight, failed to timely disclose a stock purchase in Virgin Galactic — a company directly within his oversight purview — weeks after its president testified before his subcommittee. The STOCK Act violation drew no public statement from Mast.
