Clapper spoke following Trump's sudden firing of Comey last week, which drew sharp criticism because it came amid the FBI's investigation into Russia's interference in the 2016 presidential election.
The White House had no immediate comment and no White House aide appeared on the Sunday news shows, leaving Nikki Haley, the USA ambassador to the United Nations, to defend Trump.

The New York Times reported on Friday that Comey had resisted a request from Trump that he pledge loyalty to the President. Comey earlier declined an invitation this week to testify in a closed hearing.
"All I want is for Comey to be honest - and I hope he will be". Trump calls Comey over to where he is standing in the Blue Room to offer a handshake and a partial hug, then comments that Comey has "become more famous than me".
Trump said that he wanted to move quickly to find a new Federal Bureau of Investigation director and said the potential candidates for the position were "outstanding people" and "very well known". If Republicans "start to lose a couple, or two or three look like they're not on board, that could create more pressure on the majority leader and the president to perhaps do something other than what they were planning on doing".
"Well that I can't talk about". Thirty two percent of survey respondents said they had no opinion of Trump's decision to fire America's chief law enforcement officer.
Trump welcomes Colombia's president to the White House
Mark Warner, D-Virginia, sent a letter Wednesday asking Comey to testify before the committee in both open and closed sessions. President Donald Trump has welcomed the president of Colombia to the White House for their first official meeting.
May 2, 2017: Clinton again lays part of the blame for losing the election on Comey's October 28 letter.
That startling admission fanned suggestions that Trump may be interfering with the investigation and promoted Comey allies to refute Trump's account of events. Comey also says it made him feel "mildly nauseous" to think his actions in October might have influenced the election outcome. "We have to ask ourselves what is the right thing to do and then do it". Comey had told Congress that Abedin had sent "hundreds and thousands" of emails to her husband's laptop, including some with classified information. He simply stated a fact.
Deputy Attorney General Rod Rosenstein has agreed to brief the full Senate next week on the firing of FBI Director James Comey, a spokesperson for Senate Minority Leader Chuck Schumer told reporters Friday.
May 9, 2017: Trump abruptly fires Comey. "And in fact when I chose to just do it, I said to myself, I said you know, this Russian Federation thing with Trump and Russian Federation is a made up story, it's an excuse by the Democrats for having lost an election that they should have won".
In a fresh tweet, Trump made it seem if James Comey leaks any kind of information with regard to their conversation, he would produce tapes refuting Comey's claims.
May 16, 2017: A person familiar with the situation tells The Associated Press that Comey wrote a memo after the February 14 meeting with the president that said Trump had asked him to shut down the FBI investigation into Flynn. He did not interview Saturday, but his name is on the list of people Trump is considering. He also, like Nixon, has grown increasingly isolated in the White House, recently relying on only a small circle of family members and loyal advisers while livid about the West Wing's failing efforts to get ahead of the damaging Russian Federation story, according to several people close to Trump. Rep. Jason Chaffetz, the Republican chairman of a House oversight panel, vows to get copies of any memos Comey wrote about meetings with Trump, tweeting: "I have my subpoena pen ready".
