A top aide to Kentucky Sen. Rand Paul is signaling the senator, who has strong libertarian leanings, has serious reservations about retired Army Gen. David Petraeus leading the State Department – the latest example of Paul taking issue with a potential Donald Trump Cabinet pick.

“Hillary does it -- "lock her up." Gen Petraeus does it -- CABINET POST! No.,” Doug Stafford, Paul’s chief strategist, wrote on Twitter on Monday. Trump met with Petraeus in New York City on Monday.

If Paul follows through on Stafford’s comments, it would be the third name he will have shot down to lead Foggy Bottom. A former Republican primary foe, Paul previously lambasted Trump’s consideration of former ambassador to the United Nations John Bolton and former New York Mayor Rudy Giuliani for the same post.

In an interview earlier this month with POLITICO, Paul said he would do “whatever it takes” to stop Bolton and dinged Giuliani’s support of the Iraq war.

Trump praised Petraeus after their meeting on Monday saying he was “impressed.” The general was forced to resign from his job atop the CIA in 2012, when evidence of an extra-marital affair with his biographer became public. Petraeus later pled guilty to a federal charge in connection with leaking classified information to his lover.
