Vice President Mike Pence abruptly canceled a scheduled event in New Hampshire on Tuesday, but his spokeswoman said there was “no cause for alarm.”

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

In another tweet, Farah said Pence never left Washington and there was no “emergency callback.”

The White House said Pence’s plane never left the ground in Washington.

And an administration official told reporters covering the White House that the reason was not related to Pence or President Trump’s health or because of a national security matter.

The vice president had been expected to address a roundtable discussion in Salem about the opioid crisis.

“There’s been an emergency callback,” Randy Gentry, a representative from Pence’s office, told the crowd. “The vice president was asked to return to Washington, so at this time we’re going to cancel today’s event.”
