(Reuters) A federal judge on Wednesday upheld President Donald Trump’s pardon earlier this year of 85-year-old former Arizona Sheriff Joe Arpaio, rejecting legal challenges by outside groups.

U.S. District Judge Susan Bolton said that she had considered the petitions filed by the American Civil Liberties Union of Arizona and other organizations, including one staffed by lawyers who worked for former Democratic President Barack Obama’s administration, but found no legal grounds to overturn the pardon.

Bolton did not rule on a request by Arpaio’s attorneys to take the further step of vacating his conviction.
