Tensions flared after dark Saturday — and one person was stabbed — as pro- and anti-Trump factions clashed in Washington D.C. — hours after the president himself made a drive-by appearance at a recount rally attended by thousands of his supporters.

One person was left with critical injuries in the stabbing, which occurred during a fight between two large groups at 10th Street and New York Avenue NW around 8:30 p.m., NBC 4 Washington reported, citing a spokesperson for D.C. Fire and EMS.

The victim was taken to a trauma center, according to the spokesperson.

The fight was related to the ongoing protests, officials told the outlet. No information on a suspect was immediately available.

In two separate tweets, Trump said “Antifa scum” were responsible for the violence.

“ANTIFA SCUM ran for the hills today when they tried attacking the people at the Trump Rally, because those people aggressively fought back,” the president wrote.

“Antifa waited until tonight, when 99% were gone, to attack innocent #MAGA People. DC Police, get going — do your job and don’t hold back!!!”

“Radical Left ANTIFA SCUM was easily rebuffed today by the big D.C. MAGA Rally crowd, only to return at night, after 99% of the crowd had left, to assault elderly people and families,” he later posted.

“Police got there, but late. Mayor is not doing her job!”

Videos showing Trump supporters getting cursed at and shoved by counter-protesters have flooded social media.

Counter-demonstrators hurled eggs and water bottles at MAGA supporters, in several caught-on-video instances stealing Trump flags and hats and setting them on fire.

In one incident, three Trump supporters were eating at a restaurant two blocks from the White House when someone set off fireworks in their direction, NBC 4 Washington reporter Shomari Stone tweeted.

Dramatic video captures the moment the projectiles zoomed over tables as some ducked or ran out of harm’s way.

Many Trump supporters fled to the Capital Hilton hotel after the incident, according to ABC 7 in Washington.

Officers from the Metropolitan Police Department lined up outside the hotel Saturday night in an effort to prevent demonstrators from following other people inside, the outlet reported.

Another clip captures a group of counter protesters trailing two men — identified by a photojournalist as Trump supporters — on the sidewalk — yelling “Get the f–k out of here” and throwing water from a bottle at one of them.

Footage posted by ABC 7 in Washington also captures a biker being pushed to the ground and doused with water.

After he stood up, he raised two middle fingers at the people around him.

In yet another video, a group pummeled a man and beat him over the head with a flag pole.

The poster, the host of a conservative web series, claimed the victim was a Trump supporter and his assailants were members of Black Lives Matter and Antifa.

Another clip, taken before dark, shows a man shoving and pushing another man who yelled, “Get the f–k out!” over a bullhorn.

In return, a crowd surrounded him, shoving and punching him until he face-planted on the street.

He was left dazed, bloody and barely able to stand, a separate video shows.

In total, 20 people were arrested during the protests — four for firearms violations, two for simple assault, one for assaulting a police officer, two people for acting disorderly, and one for what the Metropolitan Police Department described as “no permit,” the local NBC station reported.

It was unclear if those arrested were Trump supporters or counter protesters.

Police told the network they have responded to multiple reports of fights between protesters downtown.
