“I was all set for Bernie,” Trump told Fox News anchor Bret Baier during a town hall in Scranton, Pa., when asked who he thought would win the Democratic presidential nomination, saying that he planned to brand Sanders a “communist.”

“And then we have this crazy thing that happened on Tuesday, which he thought was Thursday,” Trump said, taking a jab at Biden, who earlier this week misidentified “Super Tuesday” as “Super Thursday.”

“I was all set for Bernie, I was ready to go,” Trump said. “I think it’s going to be very hard for him to come back.”

Biden is widely viewed as the Democratic front-runner following his strong showing on Tuesday evening. The former vice president holds an approximately 60-delegate lead over Sanders, and he’s earned a slew of endorsements from prominent Democrats in recent days.

Trump on Thursday mocked Biden for his recent gaffes a handful of times during his answer, pointing to the Democrat’s incorrect suggestion that 150 million Americans have been killed by gun violence since 2007 and his accidental remarks to supporters that he was running for the U.S. Senate.

“There’s something going on there,” Trump said.

Trump and his allies have increasingly focused on Biden’s misstatements recently and raised questions about his mental fitness for office as he surged in the Democratic contest.

At a campaign rally in North Carolina earlier this week, Trump suggested that Biden would be put “into a home” and that his administration officials would run the country for him if he were elected.

Trump also said he thought Sanders may have been “tougher” to beat “in a certain way” because of his strong base of supporters.
