President Donald Trump has said that Senator Kamala Harris is a “very unusual” and “risky” pick as a running mate by Joe Biden, PTI reported. Biden is the presumptive Democratic presidential nominee for the 2020 US presidential election, in which Trump is seeking his re-election.

Harris is the first black woman to compete on a major party’s presidential ticket. Her father is an African from Jamaica and mother an Indian.

“Look, he (Biden) made a choice. He picked her. I watched her. I watched her poll numbers go boom, boom, boom, down to almost nothing. And she left angry. She left mad. There was nobody more insulting to Biden than she was. She said horrible things about him including accusations made about him by a woman where she I guess believed the woman,” Trump told reporters on Wednesday.

Harris launched her presidential campaign in January. She had attacked Biden in a debate and was very critical of him.

“Now all of a sudden she’s running to be vice-president saying how wonderful he is. I thought it was a very unusual pick because she said such bad things. And you know better than anybody what–you know–you won’t write it because you don’t want to do that. But – you know – better than anybody she said horrible things about him. Horrible things,” Trump said.

“She mocked him. Openly mocked him. That’s why I thought that was a very risky pick. Because I’m sure that’ll be played back not necessarily by me but others. It’ll be played back,” said the president in response to a question.

In his first tweet on Wednesday, Trump called Harris “the kind of opponent everyone dreams of!”
