Four candidates are on Alaska's U.S. Senate ballot on Nov. 3, including two named Dan Sullivan. Here is where Gerald Heikes, Mary Peltola, Daniel J. Sullivan Jr. and Sen. Dan S. Sullivan stand on Iran and fishing.

The Justice Department has sued Alaska election officials to block certification of the state's U.S. Senate race unless Republican Sen. Dan Sullivan wins, arguing a second candidate named Daniel J. Sullivan Jr. could draw the senator's votes. President Trump said he ordered the lawsuit.
