A Democrat on the House Intelligence Committee said the "stunt" pulled by Devin Nunes on Wednesday not only "betrayed" the panel, but could be grounds for the Republican to forfeit his role as chairman of the committee.

Rep. Eric Swalwell told MSNBC's "Morning Joe" panel that it was irresponsible for Nunes to bypass the committee — Republicans included — altogether yet take whatever evidence he had directly to the White House.

Nunes "never, under any circumstances should have taken this information to the president," Swalwell said. "The president's campaign is under federal criminal investigation for its ties to Russia during the interference campaign. They are witnesses, essentially. To take it to them conflicts the chairman out of the duties he has."

Swalwell sidestepped the question of whether he would try to get Nunes off the committee.

"Show us the evidence that was used in this stunt yesterday," Swalwell said. "Second, what assurances can (Nunes) make that we can go forward with a credible independent investigation. He owes the American people — and most important the people on the committee — an apology."

Nunes held an impromptu press conference to announce that Trump and his campaign's communications may have been monitored as part of "incidental collection."

Now, Swalwell is calling for an independent investigation.

"I want to know why (Nunes) betrayed the independence of our work," Swalwell said. "Most of our work is done in secret. We have been able to do a lot together. This is a pretty sad departure from a long tradition of doing the people's work around national security and doing it without loyalty to the administration. Doing it with independence."
