Spurred by slowed mail delivery and attacks on the U.S. Postal Service by President Trump, concerned citizens are heading to their local post offices tomorrow (see Calendar) to mobilize in defense of one of the nation's most popular services. They'll call on Congress to safeguard the integrity of the U.S. mail and elections. "The actions will show Americans coming together to stand up for a postal system that connects us, that we rely on for medications, paychecks, and more, and that will literally be counted on to deliver democracy in the elections this fall," said AFL-CIO constituency group Pride At Work, one of the many supporters of the Day of Action.
