WASHINGTON – Two years after Mike Pence helped convince evangelical Christians to back Donald Trump's presidential bid, the vice president warned faith voters that complacency is the greatest threat to Republicans keeping control of Congress.

"The other side is mobilized, and some say they’re motivated as never before," Pence said Saturday at the Family Research Council's Voter Values Summit. "But I say we must match – in fact, I say we must surpass – the energy of the American left and their enthusiasm and passion."
