Trump brought up Coats by name at his Helsinki press conference with Vladimir Putin, then sided with Putin's claim that he didn't interfere in the elections.
Confusion over Mr Trump's position took another turn when he appeared to reject suggestions that Russian Federation might try again to influence American elections, prompting a hasty denial by the White House.
President Donald Trump on Thursday insisted he has been tough on Russian Federation, describing former President Barack Obama as a "pasty" for the Kremlin.
The Americans in question include former USA ambassador to Russia Michael McFaul and alleged crimes include fraud and corruption. Other officials familiar with the White House's scheduling say the White House has been so busy mitigating the backlash that the debriefings that would have normally taken place had yet to be conducted, The Wall Street Journal reported Thursday.
Controversy has raged over the Helsinki summit, with Mr Trump having to correct his own words from the press conference which followed it.
"We know others have the potential capability", Coats said.
An investigation into possible interference by American special counsel Robert Mueller, part of which is focused on whether there was any collusion between Trump's campaign team and Russian officials, is ongoing.
Despite the bipartisan criticism, Trump pointed blame at the media, tweeting: "The Fake News Media wants so badly to see a major confrontation with Russian Federation, even a confrontation that could lead to war. We are doing MUCH better than any other country!"
"The Summit with Russian Federation was a great success, except with the real enemy of the people, the Fake News Media", Trump wrote on Twitter.
At his joint press conference with Putin on Monday, Trump appeared to cast doubt on the conclusions of US intelligence agencies that Putin ordered the Russian government to interfere with the 2016 USA presidential election.
"I think it's imperative that he understand that he's misjudging Putin", Graham told reporters. "I don't think he was prepared as well as he should have been".
US Senate Democratic leader Chuck Schumer called for Mr Trump to reveal what he discussed with Mr Putin.
US Deputy Attorney General Rod Rosenstein, who issued the indictments against the 12 Russians last week, said on Thursday that the US would seek to warn the public in the future when it believes foreign states are trying to influence elections. "Of course, let's see how events will develop further", he said, without disclosing the nature of the agreements he referred to.
While the summit was held behind closed doors the two leaders gave a news conference afterwards at which Mr Trump shocked many by defending Russian Federation over the allegations of election interference.
That rhetoric marked a turnabout from Trump's first, upbeat description of the sit-down. Answering questions from reporters, Trump stopped short of condemning Russia's meddling in the 2016 U.S. election and appeared to take Putin's denial at face value.
In fact, committee Democrats tried to question Butina, but the Republican majority apparently shut it down so she wouldn't "tarnish" the National Rifle Association, Rep. Adam Schiff (D-Calif.) said Thursday on CNN's New Day.
Hours later, the White House stepped in to say Trump's answer wasn't what it appeared.
