President-elect Donald Trump has made his picks to head up national security and law enforcement, <br /><br /> Senator Jeff Sessions will be taking the post of Attorney General. The choice is seen as a nod to a conservative loyalist whose hardline opinions on immigration often reflected Trump’s own rhetoric.<br /><br /> Mike Pompeo came as a surprise pick to lead the CIA. The 52-year-old has also followed Trump’s line of criticising the Iran nuclear deal. In a tweet on Thursday he said he looked forward to rolling back the deal with what he called the ‘world’s largest state sponsor of terrorism’.<br /><br /> Lieutenant General Mike Flynn has been chosen as national security advisor. Announcing his appointment, Trump said he was pleased to have Flynn by his side to help ‘defeat Islamic terrorism’.<br />
