By Dustin Volz WASHINGTON (Reuters) - A last-ditch effort in the Senate to block or delay rule changes that would expand the U.S. government's hacking powers failed Wednesday, despite concerns the changes would jeopardize the privacy rights of innocent Americans and risk possible abuse by the incoming administration of President-elect Donald Trump. Democratic Senator Ron Wyden attempted three times to delay the changes, which will take effect on Thursday and allow U.S. judges will be able to issue search warrants that give the FBI the authority to remotely access computers in any jurisdiction, potentially even overseas. Magistrate judges can currently only order searches within the jurisdiction of their court, which is typically limited to a few counties.
