Trump can claim anything he wants about the prisoner exchange because Obama is never going to release the true details.
We already know the details. Obama and this government made a terrible planet changing deal with Iranians, giving them what they want and then paying them billions, and the hostages were not part of the deal.
Trump jumps in the political ring and DAILY tells the American people it’s a terrible dangerous deal which were paying them billions for and hostages were not included in the deal.
Of course Trump had a major impact here regarding the hostages.
