More than 17,000 tickets have been sold for Thursday’s Congressional Baseball Game as of this morning. And some notable guests may attend.

While President Donald Trump is not expected to be at the game, according to the organizers, the administration will be represented. Mick Mulvaney, director of the Office of Management and Budget and acting director of the Consumer Financial Protection Bureau, is expected to be the Republican’s first base coach.

The former South Carolina congressman played in the game before leaving the House.

The organizers have not yet announced who is throwing out the first pitch, but veterans will deliver the game ball as Anheuser-Busch plays a one-minute version of Budweiser’s “Service Never Stops” on the jumbotron.

Anheuser-Busch is bringing 10 of the many veterans among their 18,000 employees to the game to showcase their special beer this summer brewed by veterans.

“The beer is based on a recipe that George Washington penned while he was working in the military in New York. [It’s an] American lager. We’re going to bring some of the brew masters that brew it to the game,” said Doug Bailey, vice president of U.S. industry affairs at the company.

Two dogs will also be part of the game.

The company Rover will have Bark McGwire and Waggie Robinson, who are representing the Democrats and Republicans, respectively. They are both adoptable through Lucky Dog Animal Rescue.

Rover is asking attendees to download their app and vote for their favorite dog. The winner will be announced on Friday morning through @Rover4Govt.
