Sen. Bernie Sanders (I-VT) said on Sunday he believes Democrats’ alleged conduct in the recent controversy in the Alaska Senate race was “dumb” but “not illegal.”

While speaking with Margaret Brennan on Face the Nation, Sanders said attempts from either political party to confuse voters are “not a good thing to do.” The race between Democratic candidate Mary Peltola and Sen. Dan Sullivan (R-AK) took a turn last week when the New York Times reported that Democrats in the state allegedly recruited a retired schoolteacher named Daniel J. Sullivan Jr. so his name could appear on the ballot and pull votes away from the Republican candidate. The Department of Justice filed a lawsuit against the state but was told by U.S. District Judge Sharon Gleason on Sunday it lacked standing.
