Major League Baseball is investigating a tweet from a longtime umpire who said there would be a “cival war” if the House moves to impeach President Trump. MLB Commissioner Rob Manfred confirmed to ESPN that the organization is involved in the incident, which began when umpire Rob Drake, 50, tweeted late Tuesday that he was going to buy an AR-15 rifle “because if you impeach MY PRESIDENT this way, YOU WILL HAVE ANOTHER CIVAL WAR!!! #MAGA2020”
