Derek Levasseur, a construction worker and right-wing blogger, formally announced his campaign to unseat Sen. Susan Collins (R-Maine) in the 2020 election on Sunday.

The 44-year-old political newcomer is the second Republican to publicly say he will challenge the veteran senator during next years primary.

Im not running against Sen. Collins out of resentment, Levasseur said during a press conference. Im running for the people for common people.

Levasseur, in the opening lines of his speech, addressed a 2012 incident in which he was arrested and charged with misdemeanor domestic violence assault after a fight during his wedding reception.

Levasseur on Sunday claimed to have been defending his then-15-year-old daughter from the inappropriate behavior of two men.

In the process of doing the right thing, I made some mistakes along the way, he said. That situation has been rectified. My family has moved on.

The Senate hopeful has no criminal record after complying with the terms of a one-year deferred disposition on several charges, according to The Bangor Daily News .

Levasseur, who was a police officer at the time, was reportedly put on leave and eventually left the position. He gave up his police certification in 2013, the Daily News reported.
