Trump’s comments came as CNN reported President Trump spoke to Chinese leader Xi Jinping about Joe Biden and another 2020 campaign rival, Senator Elizabeth Warren, during a phone call in June. A record of that conversation was reportedly moved to the same highly secured computer server used to store Trump’s July conversation with Ukraine’s leader. CNN also reports Trump promised President Xi he’d remain silent about Hong Kong authorities’ crackdown on pro-democracy protests during U.S.-China trade talks.
