Washington (CNN) House Minority Leader Nancy Pelosi on Wednesday said the Trump administration's plan to brief a pair of House Republicans on a confidential intelligence source in the Russia investigation shouldn't happen.

"Tomorrow shouldn't happen," the California Democrat said at a CNN town hall Wednesday night. "There shouldn't be a Republican briefing."

"I've never seen anything like this. This is highly unusual that you would have such a briefing in the middle of an investigation, highly unusual. And that it should be partisan is just totally unacceptable," she later added.

Following outcry from Democrats on the partisan briefing, the Trump administration announced on Wednesday that it is working to brief the bipartisan "Gang of Eight" before the Memorial Day recess.

Pelosi said that the Gang of Eight, a group consisting of top Republican and Democratic members of the House and Senate intelligence committee as well as congressional leaders from both parties, would be the "appropriate venue" should there be a such a briefing.
