National Security Expert Mueller Will Deliver On Trump Russia Investigation Before Thanksgiving

A federal grand jury on Friday approved the first charges in the investigation into alleged Russian meddling in the 2016 USA presidential election, a source briefed on the matter told Reuters.

First reported by CNN, the charges remain sealed by a federal judge. It is unknown who has been charged or what the charges are.

Authorities were preparing to take anyone charged into custody on Monday, CNN reported, citing sources briefed on the matter.

The special counsel's team has also examined foreign lobbying conducted by former Trump campaign chairman Paul Manafort and former national security adviser Michael Flynn.

A CNN reporter admitted on the network Friday night that in typical cases, the person being indicted and their counsel are quickly informed of the indictment.

After Comey's ouster, Deputy Attorney General Rod Rosenstein appointed Mueller to lead the investigation.

White House press secretary Sarah Huckabee Sanders on Friday told reporters it was "a pretty big waste" for the news media to investigate connections between Trump associates and Russian Federation.

The president has repeatedly denied potential collusion as "fake news" and a "hoax" perpetuated by Democrats.

News of the charges came just one day after White House Press Secretary Sarah Huckabee Sanders had claimed the Trump administration was seeing the Russian probe "getting closer to conclusion" in an interview on Fox News' America's Newsroom.
