WASHINGTON – President Donald Trump’s review of Sen. Bernie Sanders’ appearance at a town hall forum on Fox News is in, and he’s not impressed.

“So weird to watch Crazy Bernie on @FoxNews,” Trump wrote Tuesday on Twitter. “Not surprisingly, @BretBaier and the ‘audience’ was so smiley and nice. Very strange, and now we have @donnabrazile?”

Sanders, the Vermont senator and Democratic presidential candidate, sat down Monday night with Fox News anchors Baier and Martha MacCallum for an hour-long interview before a live audience in Bethlehem, Pennsylvania.

The hour-long interview covered a lot of topics, including taxes, immigration and health care.

The appearance came just hours after Sanders released 10 years of tax returns that showed his adjusted gross income last year was $561,293. He also raked in more than $1 million in both 2016 and 2017.

"In my and my wife's case, I wrote a pretty good book,” Sanders said. “It was a bestseller, sold all over the world, and we made money. If anyone thinks I should apologize for writing a bestselling book, I'm sorry, I'm not gonna do it.”

During the town hall, Sanders also blasted Trump, calling him “dangerous” and said: “I don’t think the American people are proud that we have a president who is a pathological liar.”

Trump frequently mocked Sanders as “Crazy Bernie” when the senator from Vermont sought the Democratic nomination in the 2016 presidential campaign. Trump resurrected the nickname in February, after Sanders launched his latest bid for the presidency.

“Crazy Bernie has just entered the race. I wish him well!” he wrote on Twitter.

After Tuesday's tweet, Baier responded by extending an invitation to Trump.

"Thanks for watching Mr. President — we'd love to have you on a town hall soon — or even an interview on @SpecialReport — it's been a while," Baier wrote on Twitter. "We cover all sides."

Baier wasn't the only Fox personality to receive Trump's fire. Trump also directed his ire at Brazile, the former interim chairman of the Democratic Party and one-time Fox News critic who announced in March that she has accepted a job as on-air commentator for the cable news network.
