As bad as this all looks for the administration, it's important to note that Trump still has the backing of Republicans in Congress. House intelligence committee chair Rep. Devin Nunes, R-Calif., and other Republicans on the committee dutifully spent the Comey hearing ignoring Russian Federation and the president's false attacks on Obama.
Speaking before The House Intelligence Committee, Director Comey confirmed that the FBI is investigating Russian involvement in the 2016 election.
Before the hearing started President Trump tried to undercut those allegations by writing on Twitter, "Democrats made up and pushed the Russian story as an excuse for running a bad campaign".
Asked about Comey, White House spokesman Sean Spicer read a series of quotes from officials - some from the Obama administration - who have said they have seen no signs of collusion between Trump's campaign and Russian Federation. Majority Republicans concentrated their questions on leaks of classified information - a concern that Trump frequently mentions - and media reports on issues such as contacts between former Trump national security adviser Michael Flynn and Russian officials.
He said the investigation began in July, and by December the intelligence agencies were all agreed that there had been Russian interference, created to hurt the U.S. democracy, to damage Hillary Clinton's chances of winning, and to help Mr Trump to victory.
The intelligence community had previously said that Russia meddled in the 2016 presidential election to bolster Trump's chances and sources had said the FBI was investigating people associated with Trump's campaign for alleged communication with Russian officials during the campaign.

Trump's official Twitter account also tweeted an exchange between the Director of the National Security Agency and committee chair Devin Nunes on how there is no evidence vote totals were changed in a series of 2016 battleground states.
Les than an hour after his tweet, President Trump took to Twitter again, claiming that Mr Comey admitted that Barack Obama had the ability to "unmask" American citizens.
Media reports at the time, based on anonymous sources, said the subject of U.S. sanctions against Russian Federation was discussed.
"I can promise you", the Federal Bureau of Investigation director vowed, "we will follow the facts wherever they lead".
Russia has denied any attempts to sway the November 8 vote and Trump has rejected suggestions that he or his campaign had improper contacts with Russian officials. "So I can't answer that", Comey responded.
Comey acknowledged that "some folks may want to make comparisons to past instances" where he and other officials were more open, but he said those were about concluded investigations.
Mr Comey and NSA Director Admiral Mike Rogers were called to testify as part of their US House of Representatives Intelligence Committee's investigation into allegations of Russian interference.
Republicans, meanwhile, have sought to broaden the focus of attention to include leaks of classified information to US media.
The FBI typically does not disclose an ongoing criminal probe of any sort.
His statements echo the main findings of the January 6 USA intelligence community's report on Russian attempts to undermine the 2016 election. But the disclosure of the probe cast a cloud over the final days of Clinton's campaign.
