President Obama is receiving updates on a possible shooting at Fort Hood military base in Texas, the White House said Wednesday afternoon.

"The president has been informed of reports of a shooting at Fort Hood,” said deputy press secretary Josh Earnest, who is traveling with the president in Chicago.

“He'll continue to receive updates on the situation throughout the evening," Earnest added.

Reports Wednesday said that law enforcement personnel were responding to an active shooter situation at the Texas base.

"All personnel on post are asked to shelter in place," read a tweet from the base's official feed.

Fort Hood was the site of a mass shooting in 2009, when a U.S. Army major, Nidal Malik Hasan, fatally shot 13 people and wounded dozens more. Hasan was sentenced to death for the shooting rampage.

Obama is in Chicago to attend two events for the Democratic National Committee, and earlier Wednesday held an event in Michigan, where he pressed lawmakers on raising the minimum wage.
