Marc Fogel is finally back in the U.S. after three and a half years in a Russian prison. After that much time away in what was almost isolation, there is an acclimation process. Fogel met with President Trump at the White House after he landed in D.

One advocacy group says more than 30 American hostages and wrongful detainees are being held in other countries.

Fogel was sentenced to 14 years in prison in Russia, which the U.S. has condemned as a wrongful detention, after a small amount of medical cannabis was found in his luggage.
