Former President Donald Trump is increasingly taking aim at his successor, President Joe Biden, with a series of blistering criticisms reminiscent of last year’s campaign as the 45th president teases another run.

Trump has issued a series of statements, his substitute for Twitter, from which he was banished over his role in the Jan. 6 Capitol riot, challenging Biden’s policy decisions and circulating articles that are similarly critical of the White House’s new resident. He also appeared on Sean Hannity’s prime-time Fox News show on Monday night to take his case directly to the voters.
