Democrat warns Republicans about alleged FBI informant in the Trump campaign

A Democratic senator warned Republican lawmakers Friday against uncovering the identity of what many believe was an FBI informant inside the Trump campaign during the election.

Here's what he said

Senator Mark Warner (D-Va.) released a statement about the attempts by Republicans to discover who might have been an FBI informant on the 2016 campaign.

"It would be at best irresponsible, and at worst potentially illegal, for members of Congress to use their positions to learn the identity of an FBI source for the purpose of undermining the ongoing investigation into Russian interference in our election," he said in a statement.

Warner is the ranking Democrat on the Senate Intelligence Committee.

"Anyone who is entrusted with our nation’s highest secrets should act with the gravity and seriousness of purpose that knowledge deserves," he continued.

The Washington Post reported Friday that an FBI informant met with three members of the Trump campaign, but said there was no evidence that the FBI sent him in order to obtain information from the campaign.

CNN also reported Friday that U.S. officials told them that the confidential intelligence source did not infiltrate the campaign in order to provide intelligence officials with information.

"Bigger than Watergate!"

President Trump seized on an analysis by Andrew McCarthy of the National Review that concluded there must have been an informant in the campaign.

"Reports are there was indeed at least one FBI representative implanted," he tweeted later, "for political purposes, into my campaign for president."

"It took place very early on," he added, "and long before the phony Russia Hoax became a 'hot' Fake News story. If true - all time biggest political scandal!"
