This line can be considered to be a huge insult. Jeff Sessions is famous for being associated with American President Donald Trump and the Russian collusion scandal. He started his career as an attorney, became a Republican Senator, and was then nominated as U.S. Attorney General by Trump in 2017. He eventually became the subject of a lot of media attention over his unethical and racist actions while in office. The singer is implying that lawyers share the same type of unsatisfactory character as Jeff Sessions.
