Diehl Secures GOP Nomination For U.S. Senate, Will Debate Warren Before General

Sen. Elizabeth Warren says she and her Republican challenger, Geoff Diehl, will debate three times between now and the November election.

Diehl easily defeated his two rivals in the Republican primary on Tuesday, winning nearly 55 percent of the vote, to John Kingston's 27 percent and Beth Lindstrom's 18 percent.
