Russia: The cloud over the Donald Trump white house.

 Throughout the confusion of Donald Trump's campaign and the chaotic events of his early days in the White House, one controversy has clung to the Trump team like glue: Russia.
US intelligence agencies have concluded Moscow tried to sway the presidential election in favour of Mr Trump.

It is alleged that Russian hackers stole information linked to the campaign of his rival Hillary Clinton and passed it to Wikileaks so it could be released to undermine her.
Congressional committees were set up to investigate the matter and, in March, then-FBI director James Comey confirmed the bureau had its own inquiry.
President Trump sacked Mr Comey on 9 May, citing his reason as "this Russia thing", in a move that shocked Washington and fuelled claims of a cover up.

However, it did not halt the investigation. On 18 May, the department of justice appointed ex-FBI director Robert Mueller as special counsel to look into the matter.
Mr Mueller has not given any details of his investigation but US media have reported he is investigating Mr Trump for possible obstruction of justice, both in the firing of Mr Comey and whether Mr Trump tried to end an inquiry into sacked national security adviser Michael Flynn.

Mr Flynn resigned in February after failing to reveal the extent of his contacts with Sergei Kislyak, the Russian ambassador to Washington.
President Trump has repeatedly denied any collusion with Russia, calling the allegations a "witch hunt".
