Supporters and likely members of the far-left Antifa network and the Black Lives Matter movement were captured on video assaulting President Donald Trump supporters in Washington on Saturday.

Thousands of Trump supporters turned out for a large march to protest against alleged election fraud. Some pro-Trump marchers also engaged in violence.

While a collection of videos showed chaos and it was difficult to discern who instigated the fights, other footage from reporters on the ground showed anti-Trump protesters assaulting pro-Trump marchers without provocation.

Supporters of President Trump and counterprotesters clashed Saturday night after what was a mostly peaceful day of demonstrations in support of Trump and in protest of the election results.

One person was stabbed and more than 20 others arrested, according to local reports.

Violent clashes between Trump supporters and counterprotesters that were caught on tape by The Washington Post showed members from both sides lunging at one another. Objects can be seen being thrown through the air, and people can be seen punching one another.

Fox Business Network host Lou Dobbs grew annoyed Friday while trying to prod House Intelligence Committee ranking member Devin Nunes into explaining what Republicans intend to do to help the president contest the 2020 race.

Speaking on Fox Business Network’s “Lou Dobbs Tonight,” he not only declared the 2020 presidential election results “fraudulent” but also demanded Republicans fight it. Yet Nunes repeatedly failed to explain how the GOP intends to do exactly that.

With CNN and other media outlets including Fox News having called the election for former Vice President Joe Biden, President Donald Trump and his allies continue to argue the results were somehow fraudulent.

An exclusive interview establishes the Pennsylvania vote has major constitutional problems. Joe Kantz, the chairman of the Snyder County Commission and the chairman of the Board of Elections for more than 10 years, spoke with me yesterday about the last-minute changes the Pennsylvania secretary for elections and commissions issued. As detailed below, those changes strongly suggest that the electorally rich state the media has called for Joe Biden might have violated the Equal Protection Clause and Article II, Section 1, Clause 2 of the U.S. Constitution.

Two Pennsylvania judges served blows to President Trump’s re-election campaign on Friday, tossing out a combined six cases challenging absentee ballots.

Judge James Crumlish of Philadelphia County’s Court of Common Pleas ruled in five related cases that the Trump campaign can’t scrap a total of 8,329 mail-in ballots that it had alleged were improper because the outer envelopes lack names, dates or addresses, The Hill reported.

President Trump suffered multiple legal setbacks in three key swing states on Friday, choking off many of his last-ditch efforts to use the courts to delay or block President-elect Joseph R. Biden Jr.’s victory.

In quick succession, Mr. Trump was handed defeats in Pennsylvania, Arizona and Michigan, where a state judge in Detroit rejected an unusual Republican attempt to halt the certification of the vote in Wayne County pending an audit of the count.

President Trump and his allies have filed lawsuits alleging election irregularities or improper ballot-counting procedures in five states where President-elect Joe Biden leads.

Some suits seek to delay state officials from certifying final results, a rare step that judges likely would be reluctant to take without proof of irregularities significant enough to change the election outcome, according to legal analysts. Judges have rejected several Trump campaign and allied claims.

Imagine that, four years ago, Donald Trump lost the presidential election by 2.9 million votes, but there was no Electoral College to weight the results in his favor. In January 2017, Hillary Clinton was inaugurated as president, and the Trumpist faction of the GOP was blamed for blowing an election Republicans could have won.

The GOP would have been locked out of presidential power for three straight terms, after winning the crucial popular vote only once since 1988. It might have lost the Supreme Court, too.

Rudy Giuliani, a personal lawyer for President Trump, alleged that 650,000 ballots were counted unlawfully in the two largest cities in the state of Pennsylvania.

"We now are up to a count of about 650,000 ballots that are unlawful ballots that were cast in Philadelphia and Pittsburgh," he said in an interview with Fox Business's Lou Dobbs. "No doubt about the fact they're unlawful."
