WASHINGTON – President Donald Trump is expected to hold a news conference from the White House at 5:30 p.m. on Wednesday. I do think they are undermining their own work.”The White House says the president and vice president observe federal health guidelines, as well as those in place in the states they visit. Trips are planned with input from the presidential medical staff, and the president, vice president and senior staff are regularly tested. Democratic presidential candidate Joe Biden is painting Trump’s public appearances as public health threats. “President Trump and Vice President Pence are safely hosting events that allow them to bring their message directly to the American people in several states across the country,” said campaign spokeswoman Courtney Parella.
