A right-wing radio host said Trump needs an 'intervention from a friend' after the former president advocated for the COVID-19 vaccine

• Former President Donald Trump has advocated the COVID-19 vaccine in multiple appearances this month.
• His comments have sparked criticism from some factions of the right, including Trump supporters.

A right-wing radio host appearing on Alex Jones's Infowars said former President Donald Trump needs an "intervention from a friend" over his stance on the COVID-19 vaccines.

Trump has praised the vaccines in multiple appearances this month. During an appearance with the former Fox News host Bill O'Reilly, Trump told some people in the crowd not to boo after he revealed he'd gotten a booster shot. He reiterated his pro-vaccine stance days later in an interview with the conservative commentator Candace Owens, during which he praised the effectiveness of the vaccine at preventing severe illness.

These weren't the first times Trump had expressed support for the vaccine, but his comments prompted outrage from some factions of the right as Insider's Cheryl Teh reported.

Wayne Allyn Root, a longtime political commentator and conspiracy theorist, was one of the critics. Root is a Trump supporter and even opened for the former president at a Las Vegas rally in 2018, according to The Daily Beast.

Speaking with Jones, a radio host and conspiracy theorist, on Wednesday, Root praised the former president, saying he considers him a friend, before taking aim at Trump's vaccine comments.

"He needs an intervention from a friend because he's the greatest president of my lifetime. I love him. I will always love him," Root said of Trump.

"He's been right on everything except this issue," Root added later. "He's so horribly wrong on this issue."

Jones was also among those bashing Trump, saying on his show last week: "Hell, we're fighting Bill Gates and Fauci and Biden and the new world order and Psaki."

"And now we've got Trump on their team!" he said later.

Trump's public vaccine support also received support from White House press secretary Jen Psaki, who said the administration was "grateful" for his remarks.
