Lauren Boebert tweets about Kamala Harris while showing up to court for the first time in her son's criminal case

• Lauren Boebert attended her teen son's court hearing for his criminal theft case in Colorado.
• Tyler Boebert faces multiple charges related to car break-ins and property thefts.
• Lauren Boebert bashed Kamala Harris and Tim Walz in a tweet minutes before the court appearance.

Colorado GOP Rep. Lauren Boebert on Thursday joined her teenage son at court for the first time to support him in his criminal theft case — and fired off a tweet bashing Vice President Kamala Harris just before her son faced the judge.

Tyler Boebert , 19, dressed in a dark-colored suit and tie, appeared before the judge at the Garfield County Courthouse alongside his attorney, William Trent Palmer.

His mom sat in the first row of the courtroom wearing a yellow dress and heels as Judge John Neiley asked Tyler Boebert and Palmer whether there had been any movement in the case.

Minutes before her son's case was called, Lauren Boebert posted a message on her official X account at 8:07 a.m. local time, attacking Harris, the Democratic presidential nominee, and her running mate, Minnesota Gov. Tim Walz .

"Between Kamala Harris' 'I'm speaking' moment yesterday and Tim Walz's stolen valor being exposed, the wheels are beginning to come off the bus. Trump knows how to win. We've got this, MAGA!" read the post, which urged Lauren Boebert's followers to tune into former President Donald Trump's Thursday afternoon press conference.

By 8:13 a.m., the Republican congresswoman had taken a seat near her son in the courtroom and was seen on a livestream of the hearing typing on her cell phone. As Tyler Boebert stood before Neiley, his mom could also be seen mouthing something to him from the front row.

Tyler Boebert has had several court appearances since he was arrested by the Rifle Police Department in February in connection to a string of car break-ins and property thefts in Rifle, Colorado. During one of those court appearances, he told the judge he had trouble affording a lawyer to defend him.

This was the first time Lauren Boebert appeared in court in her son's theft case, though she previously traveled to New York City to show her support for Trump at his criminal hush-money trial earlier this year.

Boebert's chief of staff didn't immediately return a request for comment about her appearance in court.

During Tyler Boebert's Thursday court appearance, the judge asked Palmer and a prosecutor whether discussions about the case are ongoing between attorneys. Virginia Sorrell, a deputy district attorney, said that Palmer had sent her a litigation packet, which she needed to review.

The teen's next court date was set for October 10.

Tyler Boebert is facing more than a dozen charges, including several felony charges for criminal possession of ID documents.

He is one of four people accused of breaking into four cars in the city of Rifle and stealing wallets to make purchases at businesses including McDonald's, Starbucks, and gas stations, a police arrest affidavit said.

At the time of his arrest, Lauren Boebert said in a statement to BI that her son should be "held accountable for poor decisions just like any other citizen."
