Thomas Greiss issued an apology Friday night for approving of controversial Instagram posts during the U.S. presidential campaign, including one that compared Hillary Clinton to Adolf Hitler.

“I apologize for interacting with several posts that appeared in my timeline, which were wrong to engage with,” the New York Islanders goaltender said in a statement through the team, according to Newsday's Arthur Staple.

“‘Liking’ these posts was a mistake, and I sincerely apologize again."

The German goaltender, who's representing his home country at the ongoing World Championship, was criticized by the German hockey federation for his actions, prompting his apology as well as a separate one from his NHL club.

“The New York Islanders do not condone the actions of Thomas Greiss on social media and are addressing the situation internally,” the team wrote in a statement to Newsday. “And Thomas regrets his actions and recognizes that he made a mistake.”

Greiss was the Islanders' starting netminder for most of this season, appearing in a career-high 51 games at the NHL level after signing a three-year extension in January.
