WASHINGTON (AFP) - Republican challenger Tom Cotton defeated Democratic Senator Mark Pryor in midterm elections on Tuesday, media projections said, boosting chances for a shift in control of the chamber.

Cotton's win in former president Bill Clinton's home state would be the second key seat to flip to the Republican Party, which was closing in on a majority in the 100-member Senate.
