Department of Justice Special Counsel Robert Mueller will examine the June 2016 meeting between Donald Trump Jr. and a Russian attorney who allegedly was linked to the Kremlin.
An anonymous source told CNN that Trump Jr.'s conversation with Natalia Veselnitskaya would be included in Mueller's investigation to determine whether Russia meddled in the 2016 presidential election.
Trump Jr. released emails related to the meeting on July 11. Music publicist Rob Goldstone, who put Trump Jr. in touch with Veselnitskaya, wrote that information Veselnitskaya could provide "would be very useful to your father," according to The Associated Press.
Goldstone told AP in an interview that the information concerned alleged Russian donations to the Democratic National Committee.
In his emails to Trump Jr., Goldstone stated that "high level and sensitive information" was available, according to the Los Angeles Times. The information was "part of Russia and its government's support for Mr. Trump," Goldstone added.
"If it's what you say I love it especially later in the summer," Trump Jr. replied in an email.
Trump Jr. was accompanied to the June 9, 2016, meeting with Veselnitskaya at Trump Tower in New York by Jared Kushner and Paul Manafort, two top campaign advisers at the time.
Veselnitskaya has denied working on behalf of the Russian government. Trump Jr. has stated that she wanted to talk about an adoption policy suspended by Russia in retaliation for U.S. sanctions against the country contained in the Magnitsky Act.
"The woman, as she has said publicly, was not a government official," a statement from Trump Jr. released July 11 said, according to AP. "And, as we have said, she had no information to provide and wanted to talk about adoption policy and the Magnitsky Act."
Democrats took a different view, with some alleging that the meeting proves collaboration occurred between the Trump campaign and the Russian government.
"These emails show there is no longer a question of whether this campaign sought to collude with a hostile foreign power to subvert America's democracy," Sen. Ron Wyden said.
President Donald Trump later came to his son's defense.
"My son is a high quality person and I applaud his transparency," Trump said via a statement by White House spokeswoman Sarah Huckabee Sanders.
CNN requested a comment from Mueller's spokesman on the news that Trump Jr. would be part of the investigation, but Muller's office declined, citing the ongoing investigation. Attorneys for Trump Jr. did not respond to a request for comment.
