“I’m gonna be taking a lot of things that Bernie said and using them,” Trump told MSNBC’s “Morning Joe” on Wednesday morning. “I can reread some of his speeches, I can get some very good material.”
Trump said he was surprised by some of the attacks Sanders has lobbed at Clinton in the Democratic presidential race.
Sanders said “that essentially she has no right to even be running,” he said. “That she’s got bad judgment. When he said ‘bad judgment,’ I said ‘sound bite!’”
Trump reiterated his call for Sanders to mount a third-party run for president.
“Bernie has been very effective but treated very badly by the Democrats and by the Democratic Party and frankly should run as an independent,” he said.
Trump made a similar call in a tweet Tuesday.
