President Donald Trump’s son has hit back at US media reports of his meeting with a Russian lawyer who said she had damaging material about Hillary Clinton.
Donald Trump Jr denied issuing inconsistent statements about last year’s meeting.
He also suggested it was normal practice to receive information about a political opponent.
US officials are investigating alleged Russian meddling in the US election.
The president’s son-in-law, Jared Kushner, and then-campaign head, Paul J Manafort, were also at the meeting with Natalia Veselnitskaya.
Mr Trump Jr insists she provided “no meaningful information” on Mrs Clinton, his father’s rival for the presidency.
On Monday he tweeted sarcastically: “Obviously I’m the first person on a campaign to ever take a meeting to hear info about an opponent.”
He then tweeted: “No inconsistency in statements… In response to further Q’s [questions] I simply provided more details.”
And he linked to a piece in the New York Post headlined “The Times’ exposé’ on Donald Trump Jr is a big yawn”.
Later, Mr Trump Jr tweeted: “Happy to work with the committee to pass on what I know”, after a Republican member of the Senate Intelligence Committee said it should interview him.
The White House says there was nothing inappropriate about Mr Trump Jr’s meeting with the Russian lawyer.
When was the meeting and how did it come to light?
It took place on 9 June 2016 at New York’s Trump Tower, just two weeks after Donald Trump secured the Republican nomination.
It is thought to be the first confirmed private meeting between a Russian national and members of President Trump’s inner circle.
