Major League Baseball (MLB) umpire Rob Drake is bracing for the inevitable professional consequences of a tweet rant Tuesday where he threatened to buy an AR-15 automatic rifle if president Donald Trump were ever impeached. He also warned of a Civil War if Trump's impeachment ever took place.

He’s being investigated by MLB for two incendiary tweets where he threatened violence against Democrats if they impeached Trump.

The lifelong Republican and evangelical Christian seemed to have lost it when he tweeted: "I will be buying an AR-15 tomorrow, because if you impeach MY PRESIDENT this way, YOU WILL HAVE ANOTHER CIVAL WAR [sic]!!! #MAGA2020." Drake later deleted this tweet but not his follow-up tweet.

This said, "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's anger was triggered by simultaneous investigations by House Democrats into Trump's role in withholding Congressionally-approved military funds from Ukraine in exchange for Ukraine investigating and digging-up dirt on former vice president Joe Biden and his son, Hunter. This quid pro quo is considered corruption in U.S. law.

Nearly all the witnesses in the Ukraine scandal investigtions have testified behind closed doors leading the GOP to make the unfounded claim Democrats are railroading the process. Democrats point to the fact there were Republican congressmen at all these closed door hearings, which are not judicial inquiries open to the public but fact finding investigations best held in private. Republicans have also held similar closed door hearings when the need arose, which they did during the Benghazi investigations into Hillary Clinton.

After making the second tweet, Drake deactivated his Twitter account Wednesday. Joe West, president of the MLB Umpires Association, declined to talk about the incident when contacted by various media outlets.

Drake joined the Major League staff in 2010. He sports the number 30. He co-founded Calling For Christ, a professional umpire ministry.

His career as a professional MLB umpire has seen him work the 2017 World Baseball Classic won by the United States team in Los Angeles. Drake was the right field umpire for the late Roy Halladay's (Philadelphia Phillies) no-hitter in Game One of the 2010 National League Division Series (NLDS) against the Cincinnati Reds.

He was behind the plate for Felix Hernandez's (Seattle Mariners) perfect game on August 15, 2012 vs. Tampa Bay. This set a single-season Baseball record for the most perfect games in one season (three).
