White House adviser Sebastian Gorka resigns

President Donald Trump's deputy assistant, Sebastian Gorka, has resigned from the White House.

Gorka has declined to discuss the reasons he has left the White House.

However in his letter of resignation, the national security and counter-terrorism expert had expressed dissatisfaction with the current state of the Trump administration.

Posted by The Federalist website, Mr Gorka wrote that "the individuals who most embodied and represented the policies that will 'Make America Great Again,' have been internally countered, systematically removed, or undermined in recent month".
