Senator to Haspel: Where was your moral compass?
This March 21, 2017, photo provided by the CIA, shows CIA Deputy Director Gina Haspel. Senate Democrats are demanding the CIA release more information about the ex-undercover operative President Donald Trump nominated to direct the spy agency. Democrats say Haspel no longer works undercover and the public has a right to know more about her involvement in the harsh interrogation of terror suspects after 9/11. The CIA has pledged to release more information, but it's not clear if it will share details Democrats seek to illuminate Haspel's clandestine work.(CIA via AP)

CIA facing questions over Gina Haspel tweets
(CNN) —  

Gina Haspel appeared before senators of the Senate Intelligence Committee last week to make her case as to why she should be the next CIA director to replace Mike Pompeo, who became secretary of state, and she continued her effort to lobby senators this week.

Haspel’s role in the George W. Bush administration’s interrogation program was front-and-center for her confirmation hearing, where she faced pointed questions about her views on interrogation of detainees and her role in the destruction of CIA tapes.

Republicans hold a very slim – 51 to 49 – majority in the Senate, and with Kentucky Republican Sen. Rand Paul saying he’ll vote against Haspel and Republican Sen. John McCain – recovering from brain cancer treatment in Arizona – advising the Senate not to approve her nomination, Haspel’s supporters are expected to need the votes of at least a few Democrats in order to get her confirmed, though that exact number depends largely on if any additional Republicans choose to buck their party’s President.

With at least six Democrats backing her nomination as of Wednesday afternoon, her confirmation looks all but assured.

Here’s a look at the vote count so far:
