Trump ally Lindsey Graham has promised to Senate investigation into the claims of the senior justice department officials discussed invoking the 25th amendment and removing the president from power.
"The South Carolina senator, the chair of the Senate judiciary committee, told CBS Face the Nation on Sunday.
"[To] take the president down to the 25th amendment process. The deputy attorney general denies it. I promise your viewers the following, telling the truth. "
The acting FBI director referred to is Andrew McCabe. He told CBS about the discussions, which reportedly followed Trump's firing of FBI director James Comey in May 2017, in an interview this week to promote his new book. Trump fired McCabe in March 2018, just short of his intended retirement.
Rodriguez, who wrote the memo justifying, is the member of the attorney general. In The Threat: How the FBI Protects America in the Age of Terror and Trump, McCabe says Trump ordered Rosenstein to produce the memo, a claim the White House has denied.
The 25th amendment to the constitution provides for the removal of a president deemed incapable of discharging his duties. It has never been used.
The full McCabe interview was scheduled for 60 minutes on Sunday night. The reporter who conducted it, Scott Pelley, said on Thursday. McCabe also says Rosenstein is invited to wear a wire to record incriminating conversations with Trump.
Rosenstein has denied the 25th amendment or offering to wear a wire.
McCabe's book is out on Tuesday. The Guardian is an early copy, in which the discussion is about the 25th amendment or, directly, from Rosenstein to wear a wire.
Graham was a fierce rival of Trump during the 2016 Republican has become one of the president's closest allies in power.
"I think everybody in the country needs to know if it happened," he said. "I'm going to be one of the chiefs of the FBI – would go on national television and say," Oh by the way I remember a conversation with the deputy attorney if we could replace the president under the 25th amendment.
"[McCabe] I'm going to find out what happened here … I'm going to find out what happened here and the only way truth because the underlying accusation is beyond stunning. "
Asked if he would subpoena McCabe and Rosenstein to appear, Graham said: "How can I not, if that's what it takes?
"I mean, you're doing your job. Most people in the country. Mr. McCabe is know how to sell a book. But he went on national television and he made an accusation that floors me.
"… Well we're going to find out what's going to be the people who are in the know and who are telling the truth because the underlying accusation is beyond stunning."
In the House, Democrats were also planning investigations. On Saturday Adam Schiff, the chair of the intelligence panel, and Elliott Engel of foreign affairs told. They were working out the best way to take notes in private meetings between Trump and Russian President Vladimir Putin.
Part of a bitter partisan rancour and startling of the scandal, special counsel Robert Mueller is believed to be close to the conclusion of his investigation.
