WASHINGTON (NewsNation Now) — Attorney General William Barr on Monday authorized federal prosecutors across the U.S. to pursue “substantial allegations” of voting irregularities before the 2020 presidential election is certified.

As pro-Trump “Stop the Steal” rallies continued in some cities, President Donald Trump has yet to hold any official briefing since Saturday’s projected call of the presidential election for Joe Biden.

Instead, Mr. Trump has been very active on Twitter.

• Announcing the firing of Secretary of Defense Mark Esper and naming Christopher Miller as the new Acting Secretary. 
• Writing, “Nevada is turning out to be a cesspool of Fake Votes. Matt Schlapp and Adam Laxalt are finding things that, when released, will be absolutely shocking.” This tweet was flagged by Twitter.
• Writing, “Wisconsin is looking very good. Needs a little time statutorily. Will happen soon.”
• Writing, “Pennsylvania prevented us from watching much of the Ballot count. Unthinkable and illegal in this country.” This tweet was also flagged.

Pennsylvania is the state that pushed Joe Biden past the 270 electoral vote margin. Republican National Committee advisers on Monday held a press briefing to discuss postelection litigation.

“This election is not over — far from it. We have only begun the process of obtaining the accurate, honest vote count,” said White House Press Secretary Kayleigh McEnany.

McEnany told reporters she was appearing as a private citizen and adviser to the campaign. She added that the campaign wants an honest, accurate, lawful count of ballots.

“We want maximum sunlight, we want maximum transparency. We want every legal vote to be counted and we want every illegal vote to be discarded. Unlike our opponents, we have nothing to hide,” she said.

Pennsylvania is one of several states where the campaign has filed legal challenges — a number of them have been dismissed.

Earlier on Monday, Senate Majority Leader Mitch McConnell — who just won reelection in Kentucky — supported President Trump’s right to contest the election results.

“President Trump is 100% within his right to look into allegations of irregularities and weigh his legal options,” he said.

McConnell also calling out what he called “wealthy media corporations.”

“The projections and commentary of the press do not get veto power over the legal rights of any citizens including the president of the United States,” he said.

It is important to note that as of this writing, there has been no evidence presented of mass voter fraud in the election.
