CHP (Kemalist) Party MP, Eren Erdem was stopped at the Istanbul airport with his family on May 21 and his passport was seized.
When the CHP failed to nominate Erdem for MP on for June 24 elections, he lost his parliamentary seat and his immunity.
He was arrested in Istanbul on June 26th.
The Truth must NOT be expressed in Turkey.
Erdogan and Turkey supported and aided ISIS. Recruits, supplies and funds passed through the Turkish border into Raqqa and other parts of ISIS controlled Syria. The oil ISIS stole was marketed in Turkey. Erdogan no doubt personally took his cut. If Trump really wants to hurt him find and confiscate or freeze his hidden Swiss and other off shore hidden accounts.
