President Donald Trump on Friday dropped his choice of John Ratcliffe to be U.S. spy chief after questions arose about the congressman's lack of experience and possible exaggerations in his resume, marking the latest upheaval over a top national security post. 

Trump announced the move five days after he surprised many in Washington by making the conservative Republican lawmaker from Texas his selection to replace Daniel Coats as director of national intelligence, a post that oversees the 17 U.S. civilian and military intelligence agencies including the CIA. 

According to a source familiar with the situation, Trump is considering Republican Representatives Michael McCaul and Devin Nunes for the job. McCaul is a former chairman of the House of Representatives Homeland Security Committee and Nunes is a former chairman of the House Intelligence Committee. 

Trump told reporters at the White House he has "a list of three people" he will consider for the job this weekend. The Republican president blamed unflattering news coverage for Ratcliffe’s decision to bow out and instead remain in the House. Ratcliffe, 53, faced a potentially difficult Senate confirmation process. 

Trump announced last Sunday that Coats, who had clashed with him over assessments involving Russia, Iran and the Democratic People's Republic of Korea (DPRK), will step down on August 15. 

Ratcliffe, a Trump loyalist and the most junior member of the House Intelligence Committee, had been tapped, but not formally nominated, to replace Coats. 

"Rather than going through months of slander and libel, I explained to John how miserable it would be for him and his family to deal with these people," Trump said on Twitter. 

"John has therefore decided to stay in Congress.”
