"It's the only way that we can assure the American people that they can have some trust in government and that we're working to better their lives", said Collins. Trump, in a series of tweets, is making reference to what he calls "phony Trump/Russia 'collusion, ' which doesn't exist".
Mueller is investigating whether there was any collusion between members of the Trump presidential campaign and Russian Federation in connection with the 2016 election.
The president then seemed to allege that the timing surrounding the discussions over the Russian Federation investigation, which began prior to Robert Mueller's appointment as special counsel in May, were some kind of conspiracy to disrupt the GOP's push for tax reform.
"And the second thing I would look at is to see if the President of the United States is sending some kind of message to the potential defendant or other witnesses". "Give the guy a chance to do his job", he said.
The 2010 deal approved by the Obama administration while Clinton was secretary of state allowed a Russian nuclear energy agency to acquire a controlling stake in a Canadian-based company that had mining licenses for about 20 percent of USA uranium extraction capacity.
Trump was apparently referring to reports last week that Clinton's campaign and the Democratic National Committee had paid for research that was included in a salacious dossier made public in January by BuzzFeed.
Earlier, Republican-funded journalism website, The Washington Free Beacon, confirmed it has been paying Fusion GPS from the fall of 2015 to the spring of 2016 for research on then presidential candidate Donald Trump.
Known as the Steele dossier because it was compiled by former MI6 officer Christopher Steele, the document identified Russian businessmen and others whom USA intelligence analysts have concluded are Russian intelligence officers or working on behalf of the Russian government.
She added that they were most likely aware of the Democrats role in the preparation of this document.
It's unclear how much the Clinton campaign and DNC paid for the information.
Republican Susan Collins of ME, a Senate Intelligence Committee member, said Clinton's campaign chairman and the former Democratic Party head need to explain what they knew about the dossier.
On Tuesday The Washington Post, citing unnamed sources familiar with the matter, reported that the Clinton campaign had helped fund part of the research that appeared in the dossier.
In recent closed-door interviews with the Senate intelligence committee, Podesta and Wasserman Schultz said they did not know who had funded Fusion GPS, the intelligence firm that hired British Intelligence Officer Christopher Steele to compile the dossier on Trump, the sources said.
Ty Cobb, a member of the President's legal team, was forced to deny that Mr Trump's tweets on Sunday were a response to news of the latest developments in the Russian Federation investigation.
She said further that Marc Elias, a lawyer representing Hillary for America and the DNC, should be questioned "more than anyone".
Trump also tweeted Sunday about Clinton's involvement in what he called the "Uranium to Russian Federation deal", demanding that the matter receive greater scrutiny.
The House Intelligence Committee announced Saturday that Fusion GPS, the firm behind the anti-Trump files, has agreed to reveal its financial records.
Democrats have argued that these investigations are meant to distract from the probe into Russian interference in the 2016 election.
