The Department of Homeland Security said Monday that it has no information to suggest that there are threats to other public venues around the country, after a shooter killed at least 50 people and injured 400 in Las Vegas.

"At this time, we have no information to indicate a specific credible threat involving other public venues in the country," DHS said in a statement. "However, increased security in and around public places and events may be experienced as officials take additional precautions."

DHS said Duke was briefed Sunday night about the "horrific" shooting.

"The department is closely monitoring the situation and working with our federal, state and local partners in responding to and investigating this tragedy," DHS said.

"Our thoughts and prayers are with all those affected by this incident as we work to support the Las Vegas community," it said.
