President Donald Trump took to Twitter again this morning during the MSNBC morning show 'Morning Joe' to comment on Joe Scarborough and Mika Brzezinski, the show's hosts. Many were shocked by the president's personal attack on the hosts, with the head of PR for NBC News and MSNBC, chiming in on Twitter. "It's a sad day for America when the president spends his time bullying, lying and spewing petty personal attacks instead of doing his job."
