GOP CONVENTION | Ad warning that Donald Trump is too dangerous to be president

CLEVELAND (AP)

A pro-Hillary Clinton super political action committee is previewing a new "3 a.m. phone call" ad warning that Donald Trump is too dangerous to be president.

The ad starts with a picture of the White House at 3 a.m. The ads cuts to a red phone that's ringing as Trump has "just zinged another loser" on Twitter. He then complains that someone should answer the ringing phone.

"Will someone get the damn phone?" a President Trump says. "Who is calling me at 3 a.m. anyway? Total loser."

The spot mirrors an ad that Clinton ran in the Democratic primaries in 2008 against Barack Obama.
