"I'm waiting to hear from both Chairman [Johnny] Isakson [R-Ga.] and the administration about what they believe the way forward should be, and we'll take our cue from them," McConnell told reporters on Tuesday.

The Senate Veterans' Affairs Committee has postponed a confirmation hearing for Jackson, scheduled for Wednesday, amid allegations of professional misconduct.

The burgeoning scandal has engulfed Capitol Hill, with senators being peppered with questions about the allegations and what they mean for Jackson's fate.

McConnell met with Jackson late last week. He sidestepped a question Tuesday about if he knew about the allegations at the time.

Senators on the committee say they first became aware of the allegations last week. McConnell is not a member of the committee.

McConnell's comments came after Trump gave Jackson cover to withdraw his nomination questioning why Jackson would want to go forward and take the "abuse" from politicians.

CBS News reported that staffers for the Senate Veterans' Affairs Committee are looking into charges against Jackson of creating a "hostile work environment," including "excessive drinking on the job [and] improperly dispensing meds.”

Senators on the committee repeatedly declined to comment on the scope of the allegations on Tuesday, noting they had not yet been confirmed.
