(AP) — Nebraska U.S. Senate hopeful Shane Osborn is reporting that his campaign raised nearly $234,000 during the quarter that ended last month.

The Republican candidate’s campaign announced Monday that Osborn has raised $233,868 between April 1 and June 30. An Osborn spokesman says all of the money was raised in June.

The campaign spent $4,666 during that period.

Osborn, a former Nebraska state treasurer, is seeking to replace outgoing GOP Sen. Mike Johanns, who is not seeking re-election in 2014. Osborn was the first candidate to declare his candidacy.

Omaha attorney Bart McLeay announced last week that he would also run in the primary.
