Washington (CNN) House Intelligence Committee Chairman Adam Schiff defended his past comments about President Donald Trump on Sunday, disavowing calls from Republicans that he step down from leading the key committee.

"I don't regret calling out this President for what I consider deeply unethical and improper conduct," Schiff said on CNN's "State of the Union" with Jake Tapper.

He continued, "Not a bit. And I think the moment that we start to think that we should back away from exposing this kind of malfeasance and corruption is a dangerous point."

with Russia, Republicans have issued sweeping calls for Schiff to step down. As the top Democrat on the committee, Schiff has been vocal in his criticism of Trump and accused him outright of improper conduct in regard to Russian interference in the 2016 election. But after the special counsel's report, according to Attorney General William Barr's summary , said the investigation did not establish collusionwith Russia, Republicans have issued sweeping calls for Schiff to step down.

In Sunday's interview, Schiff defended his comments, saying his accusations against Trump were all incidents that were "in plain sight," including Trump's public call during the 2016 campaign for Russia to "hack Hillary's emails" and Donald Trump Jr.'s email exchange ahead of a meeting with a Russian attorney.
