Democratic vice-presidential nominee Tim Walz, along with Vice President Kamala Harris, is focusing campaign efforts on key battleground states ahead of the upcoming presidential election. Harris and Walz are kicking off a bus tour in Georgia, aiming to preserve the inroads made by Biden in 2020. The Harris-Walz campaign will also conduct a series of nationwide events over Labor Day weekend, with Walz and his wife scheduled to visit Milwaukee to support union workers. Harris will travel to Detroit and Pittsburgh, highlighting their pro-union stance and commitment to passing the PRO Act with Congress. Meanwhile, the Cook Political Report has labeled North Carolina as a 'toss-up,' and the GOP is concerned about Ted Cruz's re-election in Texas. Recently, Trump's campaign faced controversy at Arlington National Cemetery over unauthorized photo-taking.
