MLB Investigating Umpire Rob Drake's Tweet Threatening Civil War Amid Trump Impeachment Proceedings

In a tweet posted Tuesday, Drake wrote that he planned to buy an AR-15 if Trump was impeached.

Major League Baseball is investigating longtime umpire Rob Drake's tweet about buying an assault rifle amid the impeachment inquiry into President Donald Trump, ESPN's Jeff Passan reported on Wednesday.

In a tweet posted and deleted on Tuesday, Drake wrote that he planned to buy an AR-15 "because if you impeach MY PRESIDENT this way, YOU WILL HAVE ANOTHER CIVAL WAR!!! #MAGA2020." 

According to Passan, an MLB spokesperson said the league was aware of the tweet and looking into it. Joe West, the president of the MLB's Umpire Association, declined to comment to ESPN.

Drake wrote in a second tweet that "You can't do an impeachment inquiry from the basement of Capital Hill without even a vote! What is going on in this country?"

Drake, 50, became a full-time umpire in 2010 after making his major league debut in 1999. He worked postseason games in 2010 and 2012-2015.
