Donald Trump remained out of sight for a second day Wednesday recovering from COVID-19, but he made his presence known on social media as he tweeted broadsides against Democrats, floated false disease figures and pushed lawmakers to take up piecemeal economic aid proposals after nixing negotiations on a broader assistance package.White House aides said that Trump was itching to get back to the Oval Office, and preparations are under way to allow him to do so while minimizing risk to those around him.
