Republican convention gets underway two days after Trump survived an assassination attempt

The Republican National Convention kicks off on Monday, just two days after former President Donald Trump, the GOP's standard-bearer, survived an assassination attempt.

And the Saturday shooting at Trump's rally in western Pennsylvania - where one spectator was killed and two more critically injured, and the former president visibly bloodied after a bullet grazed his ear - has altered the tone and raised the stakes of the convention.

U.S. Secret Service and other officials announced on the eve of the convention that there are no plans to expand the security perimeter and that there are no known threats.
