Kristopher Drew, of California, said he received a series of life threats after being mistakenly accused of being a member of the left-wing Antifa group.

"They threaten to kill me every five minutes. I can't stand it," said Drew, who requested full anonymity on Jan. 8.

Drew is accused of having a relationship with the left-wing group Antifa after a video of himself showing a crowd supporting President Donald Trump flooded parliament on Jan. 6, to hinder Joe's victory confirmation session.

"I just came back from the Capitol Hill. We swept it, we succeeded," he said in the video.

When some people on Facebook claimed that the crowd breaking into the US parliament building was Antifa's leftist faction and not Trump's supporter, Drew voiced out the rebuttal.

"That's us. We're proud to have taken back Capitol Hill," he said, referring to the US President's supporters.

However, some people misunderstand this as a claim of responsibility by Antifa, a movement that fights against fascism on the internet and in real life.

Lin Wood, a lawyer pro-US President, shared an article alleging that Drew's video showed an Antifa member admitting they were the people who infiltrated Capitol Hill that day.

However, Drew insists he is not Antifa and that the original video he posted has been grafted.

"I never went inside the building, I was just outside, but I said we swept the Capitol Hill as a group," he explained.

For him, false accusations of videos turned into a nightmare.

At least five people have been killed after riots in a US congress building, including a woman shot dead by police and an officer on Capitol Hill.

In a video posted to his Twitter account on the evening of Jan. 7, President Trump accused protesters of entering Capitol Hill "defiling the seat of American democracy" and warned they "would pay the price".

US security officials are continuing to identify those present at the scene that day to prosecute.
