FORT MCHENRY, Maryland — Mike Pence took on the traditional role of vice presidential convention attack dog, with a denunciation of Joe Biden as a “Trojan horse” for the radical Left as he set out the “law and order” case for reelecting President Trump in a speech delivered from the birthplace of the national anthem.

The choice of Fort McHenry for the set piece Wednesday reflected organizers’ desire to incorporate historic monuments into the Republican convention, nodding to the country’s current culture wars as well as a foundational moment in America’s story.
