In 2010, Mr. Mitchell was appointed Texas solicitor general, a post he held until 2015. In 2018, he opened his own law firm in Austin, Texas.
He spent years working on legislation in Texas that would essentially outlaw abortion in the state. In 2021, the law, called the Texas Heartbeat Act, was enacted. Its enforcement established a kind of bounty system — ordinary people could file suit against those involved in performing abortions — and incentivized lawsuits by allowing plaintiffs to collect $10,000 and legal fees from those they sued.
Mr. Mitchell, who has argued before the Supreme Court five times, is also set to appear again this term. He will argue on behalf of a Texas guns rights activist in a challenge to a Trump administration law banning bump stocks, attachments that allow semiautomatic rifles to fire in sustained, rapid bursts.
Jason Murray, 38, is representing the Colorado voters who successfully challenged Mr. Trump’s inclusion on the state’s primary ballot.
This will be Mr. Murray’s first appearance before the Supreme Court, but he clerked for two of the current justices: Justice Neil M. Gorsuch, then a judge on the U.S. Court of Appeals for the 10th Circuit, and Justice Elena Kagan.
