The committee's chair, Rep. Devin Nunes (R-Calif.), also said there was no proof of Trump's allegation, if taken literally.
Cotton, a member of the Senate Intelligence Committee, said he had not seen any evidence to back Trump's wiretap claim, but he deflected a question from Tapper on whether the President should apologize to his predecessor if Comey says evidence for the President's accusation is lacking.
Two weeks ago on Meet The Press, James Clapper, the Director of National Intelligence under President Obama, denied that any evidence of such collusion existed while he oversaw the work of US intelligence agencies. It sent copies of the materials to a companion committee in the Senate, as well. Mark Warner, the committee's Democratic vice chairman, said.
The White House has faced a storm of criticism for Mr Trump's wiretapping claims which were made two weeks ago following damaging revelations about contacts between his officials and the Russian ambassador to the US Sergey Kislyak.
Devin Nunes, the Republican chairman of the United States congressional committee on intelligence, said on Sunday: "Everything I have up to this morning - no evidence of collusion".
'There is nothing at the bottom, ' he added.
The Congressional panel chief's remarks come a day before Federal Bureau of Investigation director James Comey is due to appear before the panel, facing lawmakers seeking answers about Trump's potential Russian Federation ties and the president's accusation of wiretapping by his predecessor Barack Obama. "'It never hurts to say you're sorry, '" Representative Will Hurd, a Republican from Texas, told ABC television.
"Was there a physical wiretap of Trump Tower?"
The British government immediately slapped down the claim, made by Fox's Judge Andrew Napolitano. Officials in London were livid that White House spokesman Sean Spicer cited an unsubstantiated report that Britain's Government Communications Headquarters - the British equivalent of the Central Intelligence Agency - had been used by Obama in the operation.
Spicer told a reporter in the same briefing that he was not accusing the British.

GCHQ vigorously denied the charges in a rare public statement, saying the report was "utterly ridiculous and should be ignored".
Russia's attempted interference in USA politics continues to succeed "because it created a wedge, whether real or perceived, between the White House, the intelligence community and the American public", said Representative Will Hurd, a Republican from Texas and a former CIA officer, on ABC's "This Week". I didn't make an opinion on it, ' Trump said. The Trump administration has also reiterated those denials. Speaking on NBC's Meet The Press, he added that there is "direct evidence of deception", but did not elaborate. Comey said Moscow had always been opposed to Trump's election rival, former secretary of state Clinton.
'I expect that he will.
The top Republican and Democrat on the House Intelligence Committee said Wednesday they did not have evidence to support the wiretapping accusation.
'He's sent us nothing to create jobs, no bill, no infrastructure, no accomplishment in his term of office so far, ' she said.
Democrats allege that perhaps Comey is biased: They say he was perfectly willing to talk about Hillary Clinton's emails - though Comey says he commented in that case because it was a closed investigation.
"I think it would be quite good for the administration to put forward what evidence there is", Cruz told CBS television.
Trump's sole defender in the legislature on Sunday was Republican Sen.
"You know, I will point out this is not necessarily as outlandish as everyone in the press suggests".
Sessions, a former senator and top adviser to Trump's campaign, has since recused himself from any criminal investigations tied to last year's presidential race. "Now I don't want to prejudge where we ultimately end up".
