Bauer describes himself as a " socially liberal free-market capitalist " . Although at first he claimed to have voted for Donald Trump in the 2016 United States presidential election , he later said he did not vote at all , but that he thought Trump would " shake up the system " . He has criticized American media for a liberal bias in its coverage of the president . Bauer has voiced his support of conspiracy theories such as climate change denial and the birther movement associated with Barack Obama . On May 22 , 2018 , Bauer was accused of carving BD 911 into the pitcher 's mound , a reference to a conspiracy theory that indicated " Bush did 9/11 " . Bauer later wrote on Twitter that he wrote BD 91.1 and that the numbers and letters were meaningful to him personally and completely unrelated to the September 11 attacks . Bauer has become known for his active Twitter feed , where he has argued about politics with other users , joked that one should kill himself , bragged about how smart he is , and tweeted that " 690 % " of his teammates were fellow Trump supporters . He said that the MLB Commissioner 's Office tried to censor him for sharing his opinions
