flag flap

Updated at 9:37 p.m. ET

The beginning of the national memorial for Sen. John McCain, R-Ariz., has been marred by a fight over a sign of public respect, as President Trump initially avoided issuing a proclamation to lower flags to half-staff at all federal properties in McCain's honor.

Flags were lowered at government buildings across Washington and across the country Saturday evening after McCain died, as is standard practice for a sitting member of Congress.

Voters go to the polls in Arizona and Florida today, picking nominees in critical Senate and gubernatorial races.

Weekend events could cast a pall over contests in both states, though. Arizona Sen. John McCain died on Saturday, and while it's the seat of retiring Republican Sen. Jeff Flake on the ballot Tuesday, both the late senator and President Trump — who did little to hide his disdain for McCain — have factored into the bitter primary there.
