Washington, D.C. ? A federal judge rejected a vigorous defense bid Thursday for a mistrial in the corruption case against Sen. Ted Stevens despite finding that prosecutors broke rules requiring them to turn over evidence favorable to the veteran Alaska lawmaker.

After a roller-coaster day of discord, U.S. District Judge Emmet G. Sullivan told lawyers that ending the trial after several days of testimony would be too drastic. Instead, he ordered the government to give stacks of previously undisclosed documents to the defense and called a recess until Monday.
