"Even that is possible", Trump said, when asked if it could be before he left.
"I think it's very achievable to cover pre-existing conditions without skyrocketing these premiums, without collapsing these markets", Johnson said.
"Exactly", Clapper responded. "I think the Founding Fathers, in their genius, created a system of three coequal branches of government and built-in system of checks and balances".
The FBI director also publicly confirmed that hundreds of emails Clinton sent and received contained Top Secret Special Access Program material in violation of USA law, though Comey said no "reasonable prosecutor" would take that case - a decision that was not Comey's to make and contributed to his firing.
Democrats have raised an outcry over the dismissal of Comey, who as FBI chief was in charge of the investigation into Russian meddling in the USA election.
The president also criticized Comey as a "showboat" and a "grandstander", and claimed that Comey told him he was not under investigation for collusion with Russian Federation. Initially, the White House said he had been fired because Deputy Attorney General Rod Rosenstein had expressed concern over the way Comey handled the Clinton email investigation.
If there are recordings, Republican Senator Mike Lee of Utah told the Fox News Sunday program it was "inevitable" that they would be subpoenaed and the White House would have to release them. Several associates told The New York Times that President Donald Trump had asked Mr Comey to swear his loyalty to him before he was sacked.

Noted journalist Javier Valdez killed in Mexico's Sinaloa
Do you something awesome to share with the world? Journalists shouted questions asking what would prevent them from being next. Valdez is at least the sixth journalist to be murdered in Mexico since early March.
The Federal Bureau of Investigation probe and parallel congressional investigations have cast a cloud over Trump's presidency since he took office on January 20, threatening to overwhelm his policy priorities.
Rosenstein has told officials he was unhappy with the manner in which the Comey firing took place. The pick will be under intense scrutiny since Comey was sacked while leading the Federal Bureau of Investigation's probe of possible collusion between Trump's campaign and Russian Federation. "Risky because he may be obstructing justice, in terms of the investigation that really goes to the heart of our democracy -the accountability of the President, and the people around him, to the rule of law - protecting our democracy from an invasion - a cyber-invasion by the Russians", he said.
White House Press Secretary Sean Spicer holds his daily briefing at the White House in Washington on May 3.
The furore over Comey's firing has put McCabe, the acting director, in a delicate position.
The White House has not explained further.
"I have long believed that a President can fire an FBI Director for any reason, or for no reason at all", Mr Comey wrote.
But Burr said he expects Comey will soon speak privately with members of the committee.
Speaking to CNN on Sunday, Clapper said that the "very disturbing" dismissal last week highlighted clashes between the intelligence community and the Republican president, who has been accused of getting help from Russian Federation to win the race for the White House.
