Former independent US Senate candidate Dan Osborn announced Tuesday that he will make another run for office next year, this time against GOP Sen. Pete Ricketts of Nebraska.

Osborn said he would challenge Sen. Pete Ricketts (R-Nebraska) as an independent in a race that has already gotten President Donald Trump’s attention.

Independent Dan Osborn launched another run for the Senate in Nebraska on Tuesday after having waged a surprisingly competitive, though ultimately unsuccessful, campaign last year. And Osborn said the biggest difference between last year and next year will be his Republican opponent.
