Ex-MMA thug who assaulted woman during her FaceTime call with Barron Trump learns fate

The “jealous” Russian ex-MMA fighter convicted of beating up his ex-girlfriend while she was on a January 2025 FaceTime call with President Trump’s son, Barron, was sentenced Friday to four years in prison. 

Matvei Rumiantsev, convicted of assault in January, was described as a “man given to jealousy” and “totally unrepentant” by a London judge, who accused him of not accepting blame over the attack. 

The 23-year-old was given two years for assault and two years for perverting the court of justice, sentences which will run consecutively, and was also told by the judge he may be deported from the UK due to the nature of his crimes.

The defendant was found not guilty of rape and strangulation charges related to the same date of the assault.

Rumiantsev carried out the sick assault in a drunken rage at his East London apartment after spotting an incoming call from Barron, now 20, on the woman’s phone on Jan.18, 2025, two days before Donald Trump was sworn in as the 47th president.

The woman, who was not identified for legal reasons, and Barron had been speaking after meeting on social media and Rumiantsev claimed she had called the younger Trump her “sweetheart.”

Rumiantsev grabbed the woman’s hair, choked her, called her a “s–t and w—e,” and kicked her in the stomach, the victim told Snaresbrook Crown Court, adding that she feared for her life and paid tribute to the president’s son.

“He helped save my life,” she said. “That call was like a sign from God at that moment.”

Barron called London cops after witnessing the woman sobbing on video and later sent over an emailed statement recounting what he saw.

“The individual who picked up the phone was a shirtless man with darkish hair, although I didn’t get a good look, this view lasted maybe one second and I was racing with adrenaline,” the first son’s message read.

“The camera was then flipped to the victim getting hit while crying, stating something in Russian. The guy had hung up. This whole interaction had lasted 5 to 7 seconds.”

Prosecutors said Rumiantsev had wanted to show his dominance over the victim while Barron Trump was on the call..

While behind bars, Rumiantsev wrote a letter to the victim, desperately trying to get her to withdraw the allegations.
