LANSING, Mich. (AP) — Former President Donald Trump will campaign in Michigan and Wisconsin as his campaign efforts in a handful of battleground states ramp up heading into the Labor Day turn toward the fall election. His visit to Michigan will be his third in the past seven days after he visited last week for a rally outside Detroit and on Monday spoke at the National Guard Association in Detroit. The Wisconsin visit will be his first since he attended the Republican National Convention in Milwaukee. Michigan and Wisconsin, along with Pennsylvania, make up a crucial set of swing states known as the “blue wall” that Trump won in 2017 but that President Joe Biden flipped on his way to the White House in 2020.
