David Hogg demands Mike Pence cancel NRA speech

In a tweet Sunday, Mr. Hogg noted that he had signed a MoveOn.org petition to “Demand Mike Pence cancel his speech to the NRA convention on May 4.”

The tweet to Mr. Hogg’s 777,000 Twitter followers links to a petition that makes a similar demand of Nick Ayers, the vice president’s chief of staff. The Dallas gathering is of the NRA’s political lobbying arm, not the broad membership meeting.
