"The FBI director has now confirmed what members from both parties in both the House and the Senate have said: President Obama did not order a wiretap on Trump Tower", Schumer said today.
"Well, I'm not saying that I believe that the Trump campaign was involved with Russians on this".
Trump has been dogged by allegations that his associates had ties to Russian officials.
"He probably should apologize, I think, to the President, President Obama", Panetta continued.
The ranking Democrat on the House intelligence committee, Rep. Adam Schiff of California, asked Rogers if he thought it was "utterly ridiculous" that anyone in the USA would ask British spies to do surveillance on a presidential candidate.
USA investigators say Russian President Vladimir Putin ordered the hacking into the computers at the Democratic National Committee.
Mr Flynn was sacked by the president last month after his assurances that he had not talked to Russian officials were proved to be false.
Nunes said on "Fox News Sunday" that leaks to reporters about former Trump national security adviser Michael Flynn were criminal and that his panel was probing whether other names were leaked. "It's very possible that in those wiretaps, people in the Trump Organization, their conversations were recorded".
Mr Trump has remained adamant that his claims need to be investigated, and Congress agreed to do so.
O'Reilly said that lawmakers' questions to the pair made it clear that there was a political agenda on both sides of the aisle. The British intelligence agency flatly denied the claim it happened. Neither Trump nor his administration has produced any evidence to support the claim. Rogers said it was and added that he had seen nothing at the NSA that would indicate that happened.
Richard Burr (R-N.C.) and Mark Warner (D-Va.) ― said they saw nothing to support Trump's theory: "Based on the information available to us, we see no indications that Trump Tower was the subject of surveillance by any element of the United States government either before or after Election Day 2016".
