A Manhattan federal judge on Thursday refused to move the planned Oct. 4 trial of Lev Parnas and two other men accused of funneling foreign money into U.S. elections, after defense counsel raised concerns about a series of personal and religious conflicts.

The request, which aimed to kick the trial into early next year, had injected renewed uncertainty around the high-profile criminal case, which has already been twice adjourned because of the public health crisis.
