Key moments

Wyden said Korb told bipartisan committee staff a departed acting IRS commissioner "should have been shot" for resigning and that other departing officials left to "show off their woke friends"0:22:480:23:09.

Korb called the remark "a figure of speech" taken out of context but said he wished the official "had not left when he did"0:47:570:52:33; Wyden repeatedly pressed him on whether that reflected "good judgment"0:51:180:52:46.

Sen. Hassan cited 26 USC 7217, stating it is illegal for a president or cabinet member to order an audit of a specific person and requires reporting such orders to the Inspector General; Korb repeatedly said only "I will follow the law" without directly confirming the reporting obligation, which Hassan called "hedging"1:03:381:05:28.

Wyden noted the IRS has had seven commissioners this year, including Billy Long, and tied turnover to a Trump administration plan to disclose 7.3 million taxpayer returns to ICE0:53:150:53:47.

Sen. Hassan produced customs forms showing a New Hampshire small business paying tariffs directly, after Greenstein twice declined to say whether Americans pay Trump's tariffs, deferring to the "senior trade team"1:05:521:06:56.

Sen. Warren said retroactive R&D expensing in the "big beautiful bill" will give Amazon $15 billion and Meta $11 billion this year, part of $67 billion in corporate tax breaks next year; Korb said he had not "drilled down" on the provision and could not offer a view1:35:531:38:06.

Sen. Cassidy cited a 2021 World Bank $300 million investment to electrify Ecuador's shrimp sector, saying dumped shrimp imports are bankrupting Louisiana producers per an International Trade Commission finding1:08:401:09:05.

Sen. Cortez Masto said roughly 90% of Employee Retention Tax Credit claims were found fraudulent, and business refund issuance has spiked to 2023-fraud-surge levels since the IRS lifted its processing freeze1:14:021:14:26.

Sen. Blackburn said 75% of Tennessee small businesses are pass-through entities and that Revenue Ruling 2024-14 unfairly targeted them; Korb committed to review the ruling's status1:23:381:26:46.

Korb noted this would be his fourth tour at the IRS and, if confirmed, the first time anyone served two non-consecutive terms as Chief Counsel, having previously served under George W. Bush from 2004-20080:33:120:40:21.
