The American Postal Workers Union is launching a national TV ad campaign promoting voting by mail. This comes as President Donald Trump has raised skepticism about mail-in ballots. He recently signed an executive order to put the Postal Service in the middle of election administration. The 30-second union ad features voters explaining why they vote by mail and will start airing in Ohio this week. The ad encourages voting by mail to be protected and expanded. Union President Jonathan Smith says postal workers should not be responsible for verifying voter eligibility, as would be required under Trump's order.
