Jacob Doyle Corman III (born September 9, 1964) is an American politician who served as the president pro tempore of the Pennsylvania Senate from 2020 to 2022.

[2] He was a member of the Pennsylvania Senate 1999 to 2022, holding the same seat his father, Doyle Corman, previously held.

After Joe Biden won the 2020 election and Donald Trump refused to concede while making false claims of fraud, Corman called for an audit of the election in Pennsylvania and called on Pennsylvania Secretary of State Kathy Boockvar to resign.

He supported Republican efforts to obtain a wide range of data and personal information on voters to pursue claims of fraud.

During the three-way GOP primary, Corman was attacked by the other candidates for a 1995 drunk driving conviction, as well as his admission to experimenting with marijuana in the 1980s.

[13] On the night of the election, Corman called for the resignation of Pennsylvania Secretary of State Kathy Boockvar for allowing county boards to give voters an opportunity to "cure" their ballots if they were rejected.

[16] Corman supported Republican efforts to obtain a wide range of data and personal information on voters to pursue baseless claims of fraud.

[19] On April 12, 2022, Corman filed a petition in state court to remove his name from the primary ballot, he however reversed that decision later that day saying that former president Donald Trump encouraged him to stay in the race.

The lawsuit initially aimed to require Penn State's $60 million fine to be spent on child abuse prevention in Pennsylvania, rather than across the U.S., but the suit later morphed to challenge the legality of the sanctions themselves.

[32] As part of the 2018–19 budget process, Corman identified school safety funding as a priority.

[33] In June 2019, Corman made national headlines for aggressively yelling over Democratic state senator Katie Muth, as she read into record a letter from formerly homeless resident John Boyd, who encouraged representatives to not take away monthly General Assistance funds from him and other vulnerable citizens.
