(Reuters) - President Donald Trump will travel to Minnesota on Thursday for his first campaign rally since Democrats in Washington launched an impeachment inquiry against him, his latest event in one of the states he lost in 2016 but believes he can pick up next year.

Trump’s path to re-election in November 2020 depends on clinching a cluster of farm and Rust Belt states decided by slim margins in 2016. Minnesota, which Trump lost by 1.5 percentage points to Democrat Hillary Clinton, is a key target, his campaign said.
