They're expected to call out Biden administration failures in foreign policy and promise that the Trump-Benz team will strengthen America's standing in the world.

A source tells CBS News his detail had actually been beefed up before Saturday's shooting in Pennsylvania after U.S. intelligence detected a possible Iranian plot.
