WASHINGTON— Democratic presidential hopeful Kamala Harris said Thursday that President Donald Trump should release any transcripts or notes of conversations he's had with China’s president.

Earlier Thursday, Trump declared that China should investigate former Vice President Joe Biden.

"By the way, likewise, China should start an investigation into the Bidens because what happened in China is just about as bad as what happened with Ukraine," Trump told reporters on the White House South Lawn.

Harris responded on CNN that she is “calling on the White House to actually release whatever transcripts, whatever recordings, whatever notes there are about Donald Trump’s previous conversations with (Chinese president Xi Jinping), because we need to know what he has now said in private conversations, because we obviously know what he is saying in public.”

“Clearly, he just doesn’t get it, which is that the Commander in Chief of the United States, the President of the United States, should not be in the business of working with foreign leaders against our democracy,” the California senator continued.

The president is facing an impeachment inquiry from House Democrats over a whistleblower complaint that accused Trump of "using the power of his office to solicit interference from a foreign country in the 2020 U.S. election." Trump is alleged to have used approved military aid as leverage to demand that Ukraine investigate Biden, who has generally led in Democratic primary polling.

The White House released a five-page summary of President Donald Trump's July 25 phone call with Ukraine President Volodymyr Zelensky. Trump has described the call as "perfect" and denied that the foreign aid was used as leverage to pressure Zelensky.

Democrats and other critics denounced Trump for invoking China, saying he wants yet another country to interfere in the next U.S. presidential election.

“Clearly the guy hasn’t figured out that when you solicit the help of a foreign government to interfere in the election of the President of the United States, you may be impeached. It is extraordinary,” Harris said.

Earlier in the week, Harris called on Twitter to suspend Trump's account, saying that the "words of the president matter."
