The Boston Red Sox's World Series celebration at the White House will not include the American League MVP.
Third baseman Rafael Devers said he too will not attend. Eduardo Rodriguez, Xander Bogaerts and Eduardo Nunez are also considering skipping the May 9 visit.
Abraham did not detail the reason for Betts' decision. President Donald Trump has been criticized for his treatment of and comments about minorities since taking office, and he has also rankled athletes with his vehement criticism of Colin Kaepernick.
Numerous athletes have dropped out of White House visits since Trump has taken office. The president even pulled the unprecedented move of rescinding invites to the Philadelphia Eagles and Golden State Warriors. Some Eagles players had planned to attend a scheduled meeting with Trump, but the White House pulled out in part because many players chose to skip the event.
Warriors players have almost unilaterally said they would not visit the White House while Trump is in office. They recently met with former President Barack Obama during their trip to Washington, D.C., to play the Wizards.
Red Sox players Matt Barnes, Ryan Brasier, Brock Holt, Mitch Moreland, Steve Pearce, Rick Porcello and Chris Sale have committed to meeting with Trump, per Abraham.
