President Trump has made his first on-camera comments about Democrat Joe Biden’s pick for his 2020 running mate, Kamala Harris, (D-Calif.)

Shortly after Biden announced his pick for a running mate, the president made his remarks at a White House briefing.

He said he was a “little surprised” at Biden’s selection, as her performance in the primaries was not up to par. “She did very very poorly in primaries, she ended up right around two percent,” said the president. He said she was “the number one pick” to face off against.

He remarked on her attitude towards Biden during the primaries, “She was very disrespectful to Joe Biden. It’s hard to pick someone that was that disrespectful,” said the president about a debate moment during Harris’ blitz against Biden in last summer’s primary debates.

A reporter asked President Trump about Harris’ record overseeing 1,900 marijuana convictions in San Francisco, and afterward, she claimed to have smoked marijuana, as reported by Mercury News.

“She is a person that’s told many many stories that were not true,” Trump replied, “She wants to raise taxes, slash funds to our military, she’s against fracking … she’s in favor of socialized medicine—she wants to take health care plans away from 180 million Americans.”

President Donald Trump’s re-election campaign swiftly responded to Biden’s selection of Harris, branding the pair: “Slow Joe and Phony Kamala.” “Kamala Harris ran for president by rushing to the radical left, embracing Bernie’s plan for socialized medicine, calling for trillions in new taxes, attacking Joe Biden for racist policies,” the Trump campaign said in a video tweeted by President Trump.

“They smartly spotted a phony—but not Joe Biden. He’s not that smart,” the ad continues, before adding Biden “is handing over the reins to Kamala” if the two wins in November.

During the Democrat presidential debates, the two butted heads in a heated exchange.

As Breitbart News reported: [One of the] altercation[s] was initiated by CNN when the debate’s moderators asked Harris if her position against federally mandated busing was the same as the one touted by Biden.

Harris began her response by saying it was “simply false” to claim she and the former vice president stood on the same side of the issue, before moving to a broader denouncement of Biden and his recent praise of segregationists. Harris said that on the topic, she and Biden could not “be further apart,” adding the former vice president was still refusing to acknowledge his past.

The attack echoes the one Harris launched at the first debate when she confronted Biden for praising the “civility” of two segregationists Democrats, the late Sens. James Eastland (D-Miss.), and Herman Talmadge (D-Ga.). Biden had invoked the men, who dedicated their careers to halting the progress of civil rights while touting on the campaign trail his ability to forge legislative “consensus.” The rebuke left Biden reeling to respond.

The former vice president accused Harris of mischaracterizing his record. Rather than offering proof, the 76-year-old frontrunner only muddled his stance on busing and falsely claimed to have never praised racists.

Harris tweeted after her selection as Biden’s running mate: “@JoeBiden can unify the American people because he’s spent his life fighting for us. And as president, he’ll build an America that lives up to our ideals. I’m honored to join him as our party’s nominee for Vice President, and do what it takes to make him our Commander-in-Chief.”
