Senator Jon Tester's office released a detailed summary of allegations against Ronny Jackson, Trump's pick to head the Veterans Affairs Department, on Wednesday, which range from claims of recklessly dispensing drugs to crashing a government vehicle while drunk — though Jackson denies the latter ever happened, per the AP.

Why it matters: The allegations, based on interviews with his former colleagues, add to Jackson's already tumultuous situation ahead of his now-postponed confirmation hearing. Meanwhile, the White House has vowed to vigorously defend the nominee. During today's briefing, Press Secretary Sarah Sanders characterized some of the allegations as “outrageous." Jackson told NBC News that he is "still moving ahead as planned" with the nomination.
