Rep. Tom Reed received the endorsement of President Donald Trump in perhaps the most highly-visible way — on Twitter.
Reed has served in Congress since his election in 2010. Before that, he was mayor of Corning.
Reed was the 2nd New York congressman to endorse Trump for president in 2016, then served on Trump's presidential transition team.
The 23rd Congressional District covers 11 Southern Tier and Finger Lakes counties.
Reed's challenger is Tracy Mitrano, a Democrat, cyber-security expert who worked at Cornell University and is now retired. Mitrano lives in Ithaca.
