Vice President Mike Pence canceled a planned trip to New Hampshire on Monday, his spokeswoman said, adding that it was "no cause for alarm."

A White House official said there were no medical issues with President Donald Trump or Pence.

“Something came up that required the @VP to remain in Washington, DC. It’s no cause for alarm. He looks forward to rescheduling the trip to New Hampshire very soon," Alyssa Farah, the vice president’s spokeswoman said on Twitter.

Marc Short, Pence's chief of staff, said the vice president "was called back to the White House but there's no cause for alarm and we’ll reschedule the trip soon." He said Pence's plane had never actually left Washington.

The White House would not say what issue arose to keep Pence in place.

"Something came up that required the vice president to remain in D.C. There is no cause for concern. Everybody's fine," White House spokesman Hogan Gidley told reporters.

Eary reports indicated that the vice president’s plane had been diverted to return to Washington after it was already in flight to New Hampshire, where Pence was scheduled to speak at a drug rehabilitation facility.
