Robert F. Hagan (born March 31, 1949) is an American politician and member of the Democratic Party who held a seat in the Ohio House of Representatives for the 58th District from 2007 to 2014.

During his time in there, he was chosen by the Senate Democratic caucus to serve as assistant minority whip in the 126th Ohio General Assembly; however, he stepped down from his leadership post when he entered the election for State Representative.

The bill was meant as a response to HB 515, which was a ban on adoption by homosexual or bisexual people or couples, and in presenting the fake legislation Hagan cited so-called "credible research" indicating that children in Republican households had a host of emotional problems.

Unsuccessful in his bid for Mayor of Youngstown, Hagan sought to return to Ohio House of Representatives to succeed term limited Sylvester "Sly" Patton.

[7] For the 129th General Assembly, Hagan served on the committees of Commerce and Labor; Health and Aging; and Transportation, Public Safety and Homeland Security.

[17] On October 22, 2012, Hagan introduced a bill in the Ohio House that would prohibit any team playing in publicly financed stadiums or arenas from blacking out games.

[20] On April 27, 2012, Hagan was uninvited to speak at the graduation ceremony of Mercy College School of Nursing at the request of Bishop George Murry, S.J.

[21] On April 21, 2022, Hagan stated on Twitter that he had a photo of Michael Rulli engaging in sexual relations with former President Donald Trump.

"[23] His tweet went on to claim that Republicans "jerk off to Mein Kampf"[24] On August 28, 2022, a Hagan for State Senate sign was found burnt in Youngstown's Wick Park neighborhood.

In response, Hagan blamed "extremist cowards" for the act of vandalism, stating "This is emblematic of the violent anarchy of the Republican ruling class.".

[25] In response, his opponent, Senator Rulli, denied involvement, alleging the act was an "inside job" by the Hagan campaign and offered a $5,000 reward to anyone who could provide video evidence of who burnt the sign.

Hagan denied these allegations, stating that the man in the security camera footage was not him and accused Rulli of "endangering [his] family" and "inciting violence" against him.

[27] On September 30, Hagan filed a cease-and-desist order to remove the video from social media and provided evidence that he was at home during the alleged incident.
