46th District. His Senate peers elected him Majority Leader in 2014. Cowsert's senatorial district extends into
Clarke,
Oconee, and
Walton counties. He serves on the
Senate Appropriations, Finance, Health and Human Services, Judiciary, Reapportionment and Redistricting, Regulated Industries and Utilities, and Rules committees.
Controversy Cowsert, as Vice Chair of the Senate Judiciary Committee, became embroiled in a controversial issue during the 2018 legislative session, when
The Hidden Predator Act of 2018 (HB 605) was referred to his committee. The intention of HB 605 was to reopen statutes of limitations for victims of child sex abuse, and to allow civil lawsuits to be brought against both the predator and the entities who were allegedly negligent or grossly negligent in their duty of care (i.e., concealment of known predatory behavior by a person). The legislation had previously passed the House with a 170-0 vote. Cowsert, along with other Republican committee members met to draft an amended version of the bill. When the proposed legislation came before his committee, Cowsert supported the Senate version of the bill. The Senate passed the substitute version of HB 605 by a vote of 51-0, and it was sent back to the
House. The bill's sponsor,
Jason Spencer, asked the House to insist on the language of the original bill. This insistence came on the final day of the 2018 legislative session and past the deadline for the Senate to hold a vote on reconsideration. The Senate held a vote to waive the Senate rules on reconsideration, but the vote lost in the final hours of the session, effectively killing the bill for 2018. Cowsert's law partner, M. Steven Heath, is currently defending Beech Haven Baptist Church of Athens in a current Georgia case of child sex abuse concealment. Cowsert has said he has no personal involvement in the case. His firm does not now, nor has it ever, represented the Boy Scouts of America, although some have incorrectly gleaned that from a vague reference in the Atlanta Journal-Constitution. ==Personal life==
