A Republican Louisiana senator said Wednesday he felt like he’d “dropped acid” and wanted “to heave” while reading the Justice Department’s top watchdog’s 476-page report on Russia and Donald Trump’s campaign.

“I want to thank you and I want to thank your team for your usual superb job. I haven’t read the entire report. I’m about 70% of the way through, but I’m going to finish it,” Sen. John Kennedy told Inspector General Michael Horowitz during a Senate Judiciary Committee hearing on his report.

“It is tedious. It’s supposed to be tedious. After about 15% of the way through, it made me want to heave. After about 25% of the way through, I thought I dropped acid. It’s surreal,” said Kennedy, who was expressing his disgust at the report’s findings that revealed the FBI’s mishandling of the probe.

Kennedy also called for heads to roll at the FBI and expressed bewilderment that no one had been fired.

“It’s easier to divorce your wife than it is to get fired, that’s clear, at least at the FBI,” he said.

Kennedy’s cracks came near the end of a six-hour hearing before the committee in which Republicans assailed Horowitz’s findings while Democrats focused on his conclusion that the Russia probe was not politically motivated.
