The Buffalo and Erie County Historical Society had an unusual number of high-profile visitors Friday night — four Republican Senators, including Minority Leader Mitch McConnell of Kentucky.

National Republican Senatorial Committee Chairman John Cornyn of Texas and Sens. Jeff Sessions (Ala.) and Bob Corker (Tenn.) also attended the NRSC fundraiser, which The Buffalo News said was “the first time in the memory of even the most veteran political observers that four U. S. senators convened in Buffalo at the same time.”

The $25,000-per-plate fundraiser pulled in more than $250,000, the newspaper reported, citing anonymous sources.

Former Rep. Tom Reynolds (R-N.Y), who served as chairman of the National Republican Congressional Committee during his tenure in Congress, was among the organizers of the event, as was former Republican National Committee chairman Jim Nicholson, the newspaper reported.
