Donald Trump is facing claims that a tweet about the firing of his former National Security Adviser Michael Flynn could amount to obstruction of justice, with one former government ethics official saying it could 'end' his presidency.
Responding to Mr Flynn's guilty plea for lying to the FBI as part of the federal investigation into possible links between his presidential campaign and Russia, Mr Trump tweeted: "I had to fire General Flynn because he lied to the Vice President and the FBI. It is a shame because his actions during the transition were lawful. There was nothing to hide!“
Critics jumped on the social media post, claiming it appeared to suggest that Mr Trump knew that Mr Flynn had lied to investigators before he was forced out of the administration in February.
The president then allegedly encouraging the head of the FBI to drop the investigation into Mr Flynn.
