His comments follow revelations that special counsel Robert Mueller is examining whether the president obstructed justice by firing Federal Bureau of Investigation director James Comey. During his testimony before Congress on June 8, Comey stated that he thinks Trump sacked him in order to disrupt the FBI's investigation, according to Reuters.
Trump said that "nobody has been able to show any proof yet".
US President Donald Trump announced Friday he is under investigation in connection with a probe into alleged Russian election meddling that is gnawing away at his administration - and gathering pace.
Mueller's fate "rests exclusively" with Deputy Attorney General Rod Rosenstein, Starr said. Joe Lieberman, former Oklahoma Governor Frank Keating, former FBI official Richard McFeely and acting FBI Director Andrew McCabe, met with Trump at the White House.
The Trump tweets come after the top lawyer for his transition team warned organization officials to preserve all records and other materials related to the Russian Federation probe.
DONALD Trump has said it is "sad" that seven months of investigations and hearings into possible links between his campaign and Russian Federation have been fruitless. Trump's apparent attack on Rosenstein also raised further questions about whether he will stay in his position or recuse himself from the investigation.
Trump was set to escape the Washington pressure cooker on Saturday.
In response to the stories, Trump, in tweets, expressed frustration, saying he is the target of "the single greatest WITCH HUNT in American political history".
"Why is [it] that Hillary Clintons family and Dems dealings with Russian Federation are not looked at, but my non-dealings are?"
On Thursday, Russian President Vladimir Putin said Comey had presented no evidence to prove that Moscow meddled in the U.S. election, adding that Washington had tried to influence Russian elections "year after year". "Nice", Trump wrote in his first tweet.
He followed that up 12 minutes later with a second tweet: "Crooked H destroyed phones w/ hammer, "bleached" emails, & had husband meet w/AG days before she was cleared- & they talk about obstruction?"
It also asks former transition officials to retain records related to five former Trump campaign associates: former campaign chairman Paul Manafort; his deputy Rick Gates; former foreign policy adviser Carter Page; retired Lt. Gen. Michael Flynn; and Roger Stone, a longtime Trump adviser.
