MNA� Parliament senior advisor for International Affairs said Sun. that Donald Trump�s pick of hardliner John Bolton as US national security adviser seeks to gain more concessions from the Iran nuclear deal.

�Trump�s appointment of hardliners such as John Bolton follows the same path of his policy to spread further fear and score more points from the JCPOA, the region, and Iran�s defense program,� Hossein Amir-Abdollahian said in a tweet on Sunday.

He went on to warn the US president that his policy of �squeezing Riyadh� for money would not work against the �mighty Iran�.

On March 22, Donald Trump replaced H.R. McMaster with hardliner John Bolton, who is a known to be a harsh critic of Iran and the landmark nuclear deal, as his National Security Adviser.

Iran's secretary of the Supreme National Security Council Ali Shamkhani deemed Bolton�s pick �a matter of shame� due to his ties to the terrorist Mujahedeen-e-Khalq (MEK) group.
