A Cook County judge rejected a request from legal counsel for former President Donald Trump to pause a challenge to a ruling that left him on the Illinois ballot while the U.S. Supreme Court hears arguments on the matter.

Judge Tracie Porter rejected Trump’s lawyers’ request on Wednesday, which was to halt legal proceedings until the nation’s top court rules on an appeal of the Colorado Supreme Court ruling that disqualified the former president from the ballot under the 14th Amendment. The U.S. Supreme Court began hearing arguments on the case on Thursday.
