They said Haspel, who is the acting director of the Central Intelligence Agency, was reassured that her nomination was still on track and will not withdraw. "The CIA wants her to lead them into America's bright and glorious future!"
But there are major questions about Haspel's role in the torture of prisoners.
Democrats and human rights groups have also voiced concern that as chief of staff to Jose Rodriguez, then the CIA's clandestine service chief, Haspel drafted a 2005 cable ordering the destruction of interrogation videotapes.
Unnamed national security officials and Republicans are making contingency plans, CNN reported, in case the nomination falls through. Joe Manchin of West Virginia, Dianne Feinstein of California, and Martin Heinrich of New Mexico on Monday amid speculation over which lawmakers will support her nomination. She's already acting CIA director, taking over after Mike Pompeo became secretary of State, and she's received repeated public backing from Trump, the CIA and former directors of the agency as they seek to ensure her support in the narrowly divided Senate.
Her nomination has come in for criticism even from Republicans, with Senator John McCain having said she needed to explain her involvement in one of the "darkest chapters in American history".
Trump stressed Hapel's gender in a Monday tweet touting the nomination following reports her nomination was in trouble. Were the Senate to reject her, the nominee's former colleague said, "it would send a really chilling, devastating message".

Feinstein told CBS's "Face the Nation" on April 22 that she's spoken to Haspel about the CIA's interrogation program and that the nominee "regrets it".
One of the leaders of the Women's March movement, Tamika Mallory, blamed US President Donald Trump's proposal to ban. But, he said, on Monday the agency had delivered a set of classified documents to the Senate that describe her 33-year career "including her time in C.I.A.'s Counterterrorism Center in the years after 9/11".
Later, she argued in favour of destroying almost 100 videotapes of interrogation sessions, saying the identity of the interrogators may leak out and endanger them.
During that time, Haspel reportedly was in charge of a secret prison in Thailand in 2002, where terrorism suspects were waterboarded and subjected to other "enhanced interrogation techniques".
She has told lawmakers in recent weeks that she would stand firm against any effort to restart the detention and interrogation program, administration officials told The Associated Press on Friday.
Using extreme interrogation techniques to pry information from detainees now is against the law, but some lawmakers worry that Trump will try to reinstate it and will get Haspel to go along.
