Florida lawyer Katherine Giannamore filed the complaint with the Eleventh Circuit Court, accusing District Judge Roy Altman of eroding public confidence in the judiciary's integrity and impartiality. The complaint alleges Altman used judicial resources to promote Israel, including making media appearances from his chambers and utilizing law clerks during business hours. Altman, appointed by Donald Trump in 2019, is a staunch supporter of Israel and has been promoting a self-published book defending the US ally. He has made remarks such as calling the keffiyeh a "terrorism scarf" and stating there is "no distinction" between anti-Semitism and anti-Zionism. The complaint also highlights his advocacy for a World Jewish Congress travel program that takes judges to Israel, with Altman claiming to have taken 10% of the federal judiciary on such trips.
