Donald Trump slammed former Vice President Joe Biden on Saturday, calling the potential 2020 presidential candidate “weak.”

Trump told Fox News host Jeanine Pirro during an interview on “Justice with Judge Jeanine” that Biden “was always a 1 percenter.”

“He ran two or three times, he never got above 1 percent,” Trump said.

“And then, Obama came along and took him off the trash heap, and he became a vice president, and now he’s probably leading” he added.

Trump also said Biden is “weak,” adding that “we’ll see what happens with him.”

Trump also said he is “not worried” about the competition.

“So far, I love the competition, I love what I see.”

According to Axios, Biden has told some top Democrats that he’s running for president, with rumors stating he might announce his run on Tuesday.

Even Biden’s youngest brother, Frank, told the Palm Beach Post that he expects a run.

“Now, he could surprise me,” the brother, a Palm Beach resident, told the paper. “But I know the family’s behind him 100 percent.”

Biden late last year said he believes he is the “most qualified” person to challenge Trump.

“I’ll be as straight with you as I can. I think I’m the most qualified person in the country to be president,” Biden said during a stop for his book tour in Missoula, Mont. “The issues that we face as a country today are the issues that have been in my wheelhouse, that I’ve worked on my whole life.”

“No one should run for the job unless they believe that they would be qualified doing the job. I’ve been doing this my whole adult life, and the issues that are the most consequential relating to the plight of the middle class and our foreign policy are things that I have — even my critics would acknowledge, I may not be right, but I know a great deal about it,” he added.
