Trump openly calls on Ukraine, China to investigate Biden

US President Donald Trump openly called on China as well as Ukraine to investigate his potential 2020 election rival Joe Biden, taunting Democrats seeking his impeachment for inviting foreign election interference.

Speaking in Florida, Trump blasted his accusers as "maniacs" pursuing "impeachment crap" as he sought to turn the tables on a probe that threatens to make him only the third US president ever impeached in the House of Representatives, and face a trial in the Senate.

Adam Schiff, the Democrat leading the impeachment probe in the House of Representatives, said Trump was acting "with impunity" in the face of the law.

"Once again we have a president of the United States suggesting, urging a foreign country to interfere in our presidential elections," Schiff said.

"It endangers our elections, endangers our national security and ought to be condemned by every member of this body, Democrats and Republicans alike."
"Likewise, China should start an investigation into the Bidens, because what happened in China is just about as bad as what happened with Ukraine."
Asked if he would request Xi do the same, Trump replied, "It's certainly something we can start thinking about."
Joe Biden's campaign called Trump's comments already-debunked "conspiracy theories" and accused Trump of "a grotesque choice of lies over truth and self over the country."
