“In this town, we’ve seen our share of hard times, we’ve heard our share of great promises,” said Rivers, who is not seen in adhe says in a voiceover. “But empty promises don’t build cities. We do it – with sand, sweat and cold beer.”

The announcement refers to the Trump-backed Foxconn deal, which was designed to create up to 13,000 jobs in Mount Pleasant, about 30 miles south of Milwaukee. A video was also played at the Democratic National Convention targeted Trump over Foxconn’s broken promises.

The ad also focuses on former President Donald Trump’s commentary from earlier this year calling Milwaukee a “horrible city” before the Republican National Convention, hosted at the Fiserv Forum.
