Catherine Herridge uncovered some new information that appears to link a recently-released Guantanamo Bay detainee to terrorists in Syria. 

She reported her findings this morning on "America's Newsroom," pointing to a series of tweets that were sent before Fawzi al-Odah was sent back to Kuwait on Wednesday.

The first offered congratulations to al-Odah's family, but it was sent one day before the news became public.

Investigators are now looking into how this Islamist Twitter account knew of his impending transfer. 

The message was then re-tweeted by Sanafi al-Nasr (shown below), a longtime al Qaeda operative and leader of the Khorasan group in Syria. 

Herridge also noted that 148 detainees are left at Gitmo, mostly from Yemen.

A source tells Fox News that the administration is believed to be trying to get the number below 100 to again make the argument that the remaining suspected terrorists should be transferred to maximum-security prisons inside the U.S. 

Gitmo transfers came to a sudden halt in May after backlash from the American public over the release of the "Taliban five" in exchange for American soldier Bowe Bergdahl.

Now that Republicans control the Senate, it's seen as increasingly unlikely that the military prison will be closed.

Pete Hegseth, who served at Gitmo, reacted to the developments with Bill Hemmer (below), saying the administration is lowering the standards for detainees to be released. 

Calling President Obama the "campaigner-in-chief," Hegseth said the administration is trying to push detainees out of the facility in order to keep the promise that Gitmo will be closed.

Hegseth noted that recidivism is going up, now at 30 percent, as more and more join up with ISIS and al-Nusra in Iraq and Syria.

"You don't know because you can't know. All you can do is tie elements together," said Hegseth, adding that Herridge's report seems to point toward al-Odah eventually rejoining the fight.

He is supposed to spend the next year in Kuwaiti custody.
