Federal Grand Jury Subpoenas Friend of James Comey in Classified Leak Investigation

A federal grand jury has issued a subpoena to a former FBI Director James Comey's longtime friend and advisor as part of an ongoing investigation into allegations that Comey leaked classified information. The investigation is the latest in a series of probes into potential leaks from within the US intelligence community. The former advisor was identified as one of several individuals being scrutinized over their alleged role in the leak. The subpoena marks a significant development in the probe, which is believed to be closely tied to President Donald Trump's claims that Comey did indeed leak sensitive information.
