The Massachusetts man accused of sending Donald Trump Jr. white powder in the mail is a 24-year-old who still lives in his parents’ home, has an obsession with the British royals and calls President Trump “The Dark Lord,” posts from his Facebook show.

Daniel Frisiello, who lives about 40 minutes outside Boston, used his Facebook page to criticize politicians from both sides of the aisle, including US Sen. Debbie Stabenow (D-Michigan), one of the people he sent the mysterious white powder to.

“Good god now the democrats are going of[sic] the rails,” Frisiello posted on Feb. 8 , the day after he mailed the cornstarch to Trump Jr., Stabenow and three others. He slammed Stabenow because of comments she made about Larry Nassar, the convicted pedophile accused of molesting hundreds of gymnasts. Stabenow agreed with a parent who tried to attack Nassar in court.

“This is not the democratic means and i am embarrassed to be in part of the same party as her, because i am not her. I would be offended if anyone i know in the democratic party has the dame[sic] feelings and thoughts of this imbecile of a senator!” wrote Frisiello, a registered Democrat.

He also shared various posts showing his love for the show “Glee,” including an article about former star Mark Salling — who killed himself after being charged with child pornography.

Nicola T. Hanna, interim US attorney for the Central District of California, who prosecuted Salling’s case, was one of the victims who received a letter.

“That’s for murdering Mark Salling! I Hope you end up the same place as Salling,” he allegedly wrote in the letter, according to investigators.

Frisiello also posted various news stories on the day he mailed the white powder out on Feb. 7. His first post at 1:54 p.m. was about a gay winter sports Olympian who clashed with Vice President Mike Pence because he supported conversion therapy.

Next, he shared a tweet from Disney Channel, which announced an upcoming live-action version of the early-aughts animated favorite “Kim Possible,” in which a high school student by day, superhero by night goes around the world solving crimes with her pet rat and eating tacos.

“It’s been ten long years and it’s finally here!” Frisiello wrote.

Seemingly unfazed by the federal crime he was allegedly committing that day, next Frisiello posted an article about Nancy Pelosi’s historic six-hour filibuster.

On Feb. 12, when Trump Jr. received the letter, Frisiello actually shared a news story from “ABC World News Tonight with David Muir” at 1:32 p.m., shortly after the story broke.

“JUST IN: Letter sent to Donald Trump Jr.’s apartment containing unidentified white powder, NYPD says, and opened by his wife; she and two others were decontaminated by firefighters at the scene,” a caption from the news article reads on his Facebook timeline.

Facebook commenters who learned about Frisiello’s alleged crime commented on the post.

“Dude you actually posted about your own crime? Get help,” Hugh Mungous commented Thursday afternoon.

Earlier that morning, Frisiello shared a post from the ACLU and a video of the Smithsonian’s unveiling of Michelle and Barack Obama’s portraits.

Throughout his Facebook pictures and timeline posts, references to the British royals appear, including a post that said he was America-born but British at heart. He also has a photo of him bowing to what appears to be a wax sculpture of Queen Elizabeth.

He shared supportive posts about Ivanka Trump, slammed Meghan Markle for getting involved with “American problems,” and called Eric Trump “Tweedle Idiot.”

Frisiello, who’s been placed on leave from his job at Catholic Charities of Boston’s Peabody child care center, has a photo of him with Congressman Seth Moulton (D-Massachusetts) at the state Democratic convention in 2016. A spokesperson for Moulton said Frisiello never worked with his office and they denounce violence and threats.

The troubled man — who neighbors say was quiet, kept to himself, and drove an older, small green car — also appeared to have a penchant for conspiracy theories.

On Jan. 31 after an Amtrak train carrying Republican members of Congress crashed, Frisiello implied it wasn’t an accident.

“This is a hit job,” he wrote.
