It is his most direct statement so far on the reason for Donald Trump Jr’s meeting with Kremlin-linked lawyer Natalia Veselnitskaya in June 2016.
Special Counsel Robert Mueller is investigating US intelligence findings that Russians conspired to sway the election in Mr. Trump’s favor.
On Sunday, US media including the Washington Post, CNN and AP reported that Mr. Trump was worried Donald Trump Jr could be in legal trouble because of the 9 June 2016 meeting with Ms. Veselnitskaya. They cited multiple unnamed sources.
The President denied that he is worried about the Trump Tower meeting in a Twitter post Sunday morning.
The explanations about the reason for the meeting from Trump Jr., the White House and the President’s legal team have changed and been contradictory over time. In a statement to The New York Times last summer, Trump Jr. said the meeting was primarily about a program for Americans to adopt Russian children.
Mr. Trump’s latest tweet appears to contradict a previous statement from the Trump camp about the meeting.
However, he subsequently admitted he had agreed to the meeting after being told he would be offered information that would prove detrimental to Mrs. Clinton. He also released the email exchange that brought about the meeting.
US media then reported that the US president had been involved in the initial statement his son issued on the meeting.
This was initially denied by Mr. Trump’s team, but his lawyers later confirmed that he had in fact dictated his son’s statement.
US commentators have argued that Mr. Trump’s new admission that the meeting was to gain information about Mrs. Clinton shows that the earlier statement was misleading.
However, legal experts say that Mr. Trump Jr could fall foul of campaign finance laws, which prohibit accepting anything of value from a foreign government or foreign national.
His apparently enthusiastic response to the offer of information about Mrs. Clinton could also breach conspiracy laws.
