White House press secretary Sarah Sanders accused a former Clinton aide on Saturday of admitting to being "damn glad" Hillary Clinton's team "colluded" with Russia during the 2016 election.

"Clinton spokesman just said he's 'damn glad' Clinton campaign colluded [with] Russia to spread disinformation about @POTUS & influence election," Sanders tweeted in reference to a comment made Friday by former Clinton campaign spokesman Brian Fallon.

Fallon told The Washington Post a day earlier Marc Elias, the top lawyer for Clinton's presidential campaign, did the right thing by hiring a private research firm to look into Donald Trump last spring.

Fusion GPS, the firm Elias hired using campaign funds, ultimately produced the so-called Steele dossier that contained salacious accusations against then-candidate Trump.

A spokesperson for Elias later confirmed he had been briefed on material contained in the dossier but never received a copy.

"Marc is known as one of the most skilled professionals in Democratic politics, in addition to being the party's top election lawyer," Fallon said.

He continued, "I am damn glad he pursued this on behalf of our campaign and only regret more of this material was not verified in time for the voters to learn it before the election."

Sanders, along with some Republican officials, have accused the Clinton campaign of colluding with Russia in the days since it was first reported that campaign funds belonging to the former Democratic presidential hopeful funded the project that led to the dossier.

The author of the dossier, former British spy Christopher Steele, is a Russian expert and has been accused by some of filling the dossier with damning information provided by Kremlin officials.
