Sebastian Gorka, President Donald Trump’s chief anti-terrorism adviser accused of ties to a far-right Hungarian organisation, is to leave the White House, it has been reported.

The British-born aide moved to the US from Hungary in 2012. It was claimed that in an interview with Hungarian TV unearthed by the American press, Mr Gorka voiced his support for the Magyar Garda, a fascist militia.

The footage led to calls for Mr Trump to fire him, with a spokesman for the NGO Human Rights Firstclaiming the White House was “harbouring a man who has made a career out of associating with racists and antisemites”.

That allegation gained traction when earlier this year leaders of the antisemitic group Historical Vitézi Rend said Mr Gorka was an official member.

The group is a namesake of Vitézi Rend, a defunct order of merit that existed as a state entity for 20 years until 1944 under the rule of Miklos Horthy, Hungary’s Nazi-allied leader. It was then disbanded and outlawed.

The revelations led to pressure on the president from Eliot Engel and Nita Lowey, both Jewish members of the House of Representatives, who wrote to Mr Trump urging him to fire Mr Gorka.

Political website The Hill reported that Mr Gorka, who in his current role as deputy assistant to the president advises on counter-terrorism, will be leaving for a position in an unspecified federal agency.
