Former GOP speechwriter Tim Miller, host of "The Bulwark Podcast," on Thursday roasted a MAGA star's recent remarks about conservative activist Charlie Kirk's murder in September.

Tucker Carlson, a MAGA media personality, appeared on a recent episode of "This Past Weekend," a podcast hosted by comedian Theo Von. During the episode, Carlson told the audience that they shouldn't trust the FBI's investigation, and floated theories suggesting a foreign government may have been involved.

Those comments piqued Miller's interest considering that Carlson is friendly with several people in President Donald Trump's administration, including the people with direct involvement in the investigation.

"This is crazy," Miller said on a episode of "Bulwark Takes" on Thursday. "How can anybody accept this? If Tucker is concerned that they're not taking this investigation seriously, he should call [FBI Director] Kash Patel, who he's friends with, and [Deputy FBI Director] Dan Bongino, and Donald Trump, and say they should take this seriously."

"If Tucker doesn't trust those guys, who does he trust?" Miller continued. "Could anybody do this investigation seriously? Does he trust the regular Utahans that are going to sit on a jury and decide this?"

Carlson's comments come at a time when Tyler Robinson, who is accused of killing Kirk, made his first appearance in court on Thursday. Robinson, 22, turned himself into authorities after the September 10 shooting.

Robinson has been charged with aggravated murder and has not yet entered a plea. Prosecutors have said they will seek the death penalty.

"I could see why an anti-Trump person who doesn't trust Kash Patel might think that that they don't trust Cash Patel ... but why would Tucker not trust them?" Miller wondered.
