As Massachusetts’ Sept. 1 U.S. Senate primary election approaches, Democrats Sen. Ed Markey and Rep. Seth Moulton will debate for a third time Aug. 20 in Boston.

PolitiFact is fact-checking the debate live at 8 p.m. EDT with our partner WCVB-TV, which is cohosting the debate with WBUR-FM and The Boston Globe. We previously fact-checked Markey and Moulton’s July 8 and Aug. 3 debates, as well as Moulton’s June 16 debate against Republican candidate John Deaton.
