“We’ll highlight the differences in the way Hillary Clinton was prosecuted and how my client was prosecuted,” Saucier's attorney Ronald Daigle told Fox News. “We’re seeking to cast a light on this to show that there’s a two-tier justice system, and we want it to be corrected.”

During his 2016 trial, Saucier’s lawyers invoked Clinton’s alleged mishandling of classified information, arguing that there was a double standard in how his violation was handled.

“They interpreted the law in my case to say it was criminal, but they didn’t prosecute Hillary Clinton,” Saucier told Fox News. “Hillary is still walking free. Two guys on my ship did the same thing and weren’t treated as criminals. We want them to correct the wrong.”

The FBI did not charge Clinton over her use of a private email server, though then-FBI Director Comey said her use of a private email server was "extremely careless."

Saucier was highly critical of Obama officials’ handling of his case, claiming that it was politically motivated and that he was used “as an example” because of the Clinton investigation.

Trump also made the comparison between Saucier and Clinton, mentioning Saucier’s case during the campaign and tweeting about it earlier this year.

“Crooked Hillary Clinton’s top aid, Huma Abedin, has been accused of disregarding basic security protocols,” Trump tweeted just months before pardoning Saucier. “She put Classified Passwords into the hands of foreign agents. Remember sailors pictures on submarine? Jail! Deep State Justice Dept must finally act? Also on Comey & others.”
