A little-known candidate has suspended his campaign for the Democratic nomination for a U.S. Senate seat representing Indiana.
Martin Del Rio wrote Tuesday night on his Facebook page that "due to unforeseen circumstances, it is no longer possible for me to continue my campaign and be placed on the primary ballot."
The Highland resident had said he intended to run against Sen. Joe Donnelly in the May 8 Democratic primary election. He filed a statement of organization in October with the Federal Election Commission.
Del Rio would have had to collect the signatures of 500 certified registered voters in each of Indiana's nine congressional districts by Feb. 9 to qualify as a candidate in the primary election.
He had identified himself on his campaign website as an Iraq war veteran and an advocate in the Army Wounded Warrior Program.
Jim Wieser, chairman of the Lake County Democratic Party, said in November that he had never known Del Rio "to be involved in any political activity whatsoever."
