US President Donald Trump blasted on Thursday what he called a "phony story" that he is being investigated for obstruction of justice by a special counsel probing alleged Russian meddling in the 2016 US election and possible collusion with his campaign. "Witch Hunt", he wrote on Twitter.
In a pivotal shift in the investigation that has riveted Americans like no other in decades, senior intelligence officials have agreed to be interviewed by investigators working for the special counsel, Robert Mueller, the Post said.
"I know I'm not under investigation", Trump told NBC's Lester Holt in a May 11 interview that came just two days after Trump had fired Comey over, according to the President, the FBI director's handling of the Russian Federation investigation.
The Post cited anonymous sources who were briefed on requests made by investigators.
Mark Corallo, a spokesman for Trump's private attorney, Marc Kasowitz, immediately condemned the Post report.
The letter said the investigation will also probe Comey's testimony that Loretta Lynch, as President Obama's attorney general, had directed him to describe an FBI probe into Hillary Clinton's email practices as merely a "matter" and to avoid calling it an investigation.
It goes on to tell RNC members to say: "If this leaked account is true, it means the special counsel has struck out on trying to prove collusion and is shifting to obstruction in an effort to save face".
"Coons's comment came hours after Trump called the investigation into Russia's meddling in the 2016 presidential election and possible ties between his campaign staff and Russian Federation the "single greatest WITCH HUNT in American political history". The outlet also said the probe now also includes a look at any financial crimes by Trump associates.
USA president Donald Trump has told his Twitter followers that they are witnessing the "single greatest witch hunt in American history".
It was not clear if Trump's comment was based on news reports or if the White House had been given official notice.
The former Federal Bureau of Investigation director also discussed detailed memos he kept after his interactions with Trump because "I knew there might come a day where I might need a record to defend not just myself but the Federal Bureau of Investigation".
One meeting under scrutiny was said to be that of Mr Trump and Mr Coats on March 22.
