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.
This development comes as Robert Mueller continues to incorporate Trump's Twitter history into his investigations of Russian collusion and obstruction of justice. One person allegedly in attendance, former Deputy Campaign Chairman Rick Gates, is now a cooperating witness in Special Counsel Robert Mueller's Russian Federation investigation.
President Donald Trump singles out the media during his rally on August 2, 2018 at the Mohegan Sun Arena at Casey Plaza in Wilkes Barre, Pa.
Trump campaign officials sat down in June 2016 with a Kremlin-linked lawyer who promised dirt campaign rival Hillary Clinton. He initially denied he met with any Russians on behalf of the campaign and now he admits the meeting was to get damaging information about Clinton. "I believe it's in the best interest of the president and of the United States of America and the American people for that investigation to run the course, for all the truth to come out".
Trump Jr respond.ed "I love it", when first offered the political "dirt" on Clinton, the Democratic presidential nominee.
News of the meeting, which Trump's son-in-law Jared Kushner and top campaign official Paul Manafort also attended, broke in July 2017. Last week, however, he adopted his lawyers' tactics and insisted "collusion is not a crime".
While "collusion" is not mentioned in USA criminal statutes, Mueller is investigating whether anyone associated with Trump coordinated with the Russians, which could result in criminal charges if they entered into a conspiracy to break the law, including through cyberhacking or interfering with the election.
The infamous meeting was thrust back into the spotlight last month after Trump's former personal attorney, Michael Cohen, alleged Trump approved the meeting.
President Trump doubled down on his stance, proffered a year ago, that pursuing damaging information on Hillary Clinton was the focus of a questionable 2016 meeting between his son Donald Trump Jr. and a lawyer with ties to the Kremlin. Trump's lawyers acknowledged in a letter to Mueller's team in January 2018 that Trump dictated the response, according to the Times. Paul Manafort, who ran Trump's campaign at a crucial time leading into the Republican National Convention, is now on trial on charges concerning his previous business activities that grew out of Mueller's probe.
"I wasn't involved in the statement drafting at all, nor was the president", Sekulow claimed in July 2017.
"I had bad information at that time", the lawyer said.
