WASHINGTON, March 19 (Reuters) - Former FBI Director James Comey has been subpoenaed by federal prosecutors in Miami as ‌part of the U.S. Justice Department's investigation into former ‌officials who have previously probed and prosecuted President Donald Trump, CBS News ​and Axios reported on Thursday, citing sources.

The investigation has produced more than 130 subpoenas since cranking up last year, and targets top officials who worked under former presidents Barack Obama and Joe ‌Biden, Axios reported.

The ⁠Justice Department did not immediately respond to a request for comment. A representative of Comey could ⁠not be reached. Comey's attorneys declined to comment to CBS News.

Reuters reported late last year federal prosecutors were preparing grand jury subpoenas ​to investigate ​Obama-era intelligence officials who produced ​an assessment that Russia interfered ‌in the 2016 presidential election that Trump won.

Comey oversaw an investigation into whether Russia and Trump's 2016 campaign colluded with Russia. Trump's firing of Comey prompted then-Deputy Attorney General Rod Rosenstein to appoint Special Counsel Robert Mueller.

Mueller's investigation dogged much ‌of Trump's first term. He ultimately ​concluded there was no evidence of ​a criminal conspiracy between ​Trump's campaign and Russia.

The Trump Justice Department has ‌also faced some legal and judicial ​roadblocks as ​it pursues investigations into critics and antagonists of the president during his second term.

A judge in November dismissed indictments ​against Comey and ‌New York state Attorney General Letitia James, who each ​previously led investigations into Trump.
