Donald Trump Jr. mocked the attack on House Speaker Nancy Pelosi's husband Paul on social media by sharing a "Halloween costume" intended to represent the hammer-wielding intruder.

Trump Jr. shared an image Sunday night showing a hammer lying on top of a pair of Hanes underwear with the comment: "Got my Paul Pelosi Halloween costume ready."

"The internet remains undefeated … Also if you switch out the hammer for a red feather boa you could be Hunter Biden in an instant," Trump Jr. wrote.

He also posted a screenshot of the image on his Instagram, racking 88,000 likes. The underwear in his post appears to reflect a debunked rumor that the intruder was in his underwear at the time of the attack.

The skepticism regarding the incident seems to have grown after Evan Sernoffsky, a reporter at the Fox-affiliated local news outlet KTVU, tweeted that the attacker was in his underwear at the time of his arrest. Sernoffsky deleted the tweet and said that sources told him this was untrue.

Some people have even floated the baseless conspiracy theory that Paul Pelosi and DePape were lovers.

The Telegram channel for Bannon's "War Room" show shared a story from "The Republic Brief" that repeated some of "the same uncorroborated details about the encounter, including that the suspect was found in his underwear," the Washington Post reported.

D'souza also amplified the theory on his Twitter.

"Were Paul Pelosi and his attacker BOTH in their underwear? BOTH holding hammers? And the attacker didn't strike until AFTER police were on the scene? As a movie-maker, I gotta say this script must be rejected. Nothing about the public account so far makes any sense," he wrote.

Some conservatives have tried to spin the apparently politically motivated attack by tying it to crime in San Francisco. "Last Week Tonight" host John Oliver on Sunday called out right-wing claims linking the attack to bail reform after Rep. Michael McCaul (R-TX), complained on Fox News about letting "dangerous criminals" roam free and commit violence. McCaul suggested that the intruder who attacked Paul Pelosi was out on bail.

"Now, he's wrong about a few things there. Again, the suspect was not out on bail. Also, no one gets bailed out of prison—that's where convicted people go," Oliver said.

People have continued to spread falsehoods about the hammer attack, including new Twitter owner Elon Musk, who amplified a baseless conspiracy theory from a site suggesting that Paul Pelosi was drunk and in a fight with a male prostitute. "There is a tiny possibility there might be more to this story than meets the eye," Musk wrote before deleting the tweet hours later.
