New U.S. House districts in Florida are facing their first test in court. A state judge is set to hear arguments Friday on a request to block the new districts from being used in the midterm elections. Several lawsuits contend the districts violate a state constitutional provision against partisan gerrymandering. Republicans already hold 20 of the state’s 28 U.S. House seats. The new districts signed into law by Republican Gov. Ron DeSantis could improve Republicans' chances to win four additional seats. Florida is one of several states to redraw congressional districts after President Donald Trump urged Republicans to do so.

Voting rights groups are arguing that a federal judge should stop President Donald Trump's executive order restricting mail voting because he doesn’t have the authority to do so. Lawyers for the groups made their arguments Thursday during a hearing before a federal judge. They are seeking a temporary restraining order against Trump's executive order issued earlier this year. Trump directed the federal government to compile a list of eligible voters in every state and the Postal Service to refuse to deliver ballots for those not on it. Democrats and voting rights groups sued to block it. They argued the Constitution gives control of elections to states, not the president.

The Justice Department is challenging efforts to sanction attorneys from the first and second Trump administrations, asserting in a lawsuit that the District of Columbia Bar is unfairly playing politics with the legal disciplinary process. The lawsuit represents a direct challenge to the authority of the office that enforces ethics standards for attorneys in the nation’s capital where several high-profile investigations of Trump-allied lawyers are playing out. The lawsuit was filed Wednesday in federal court in Washington. The D.C. Bar’s Board on Professional Responsibility did not immediately respond to an email seeking comment.

The widow of a man killed in a mass shooting at Florida State University is suing ChatGPT maker OpenAI, blaming the artificial intelligence chatbot for contributing to the tragedy. The lawsuit says the alleged gunman Phoenix Ikner relied on ChatGPT to determine what type of gun to use and which location would allow for the most potential victims, among other information. The lawsuit was filed by Vandana Joshi. Her husband was one of two people killed and six others were wounded. She said in a statement Monday that “OpenAI knew this would happen." OpenAI denies wrongdoing.
