(CNN) New revelations about Donald Trump Jr.'s meeting in June 2016 with a Russian lawyer have rocketed the President's eldest son to the center of allegations of collusion with Russia.

Here's a look back at the steady drip of disclosures and shifting statements from Trump Jr. and others involved -- which have triggered a mounting list of questions.

July 8

First New York Times story breaks

Trump Jr. doesn't disclose meeting's full purpose

Donald Trump Jr. stands in April 2017, at the White House.

His statement: "It was a short introductory meeting. I asked Jared (Kushner) and Paul (Manafort) to stop by. We primarily discussed a program about the adoption of Russian children that was active and popular with American families years ago and was since ended by the Russian government, but it was not a campaign issue at the time and there was no follow up."

"I was asked to attend the meeting by an acquaintance, but was not told the name of the person I would be meeting with beforehand."

NYT reports Trump Jr. was told contact had info damaging to Clinton

The Times, citing multiple sources, including three advisers to the White House, reports that Trump Jr. was "promised damaging information about Hillary Clinton before agreeing to meet with a Kremlin-connected Russian lawyer."

Trump Jr. issues a new statement

Trump Jr. tells the news media : "After pleasantries were exchanged the woman stated that she had information that individuals connected to Russia were funding the Democratic National Committee and supporting Mrs. Clinton. Her statements were vague, ambiguous and made no sense. No details or supporting information was provided or even offered. It quickly became clear that she had no meaningful information. She then changed subjects and began discussing the adoption of Russian children and mentioned the Magnitsky Act. It became clear to me that this was the true agenda all along and that the claims of potentially helpful information were a pretext for the meeting."

Paper reports Trump Jr. knew of Russian effort

The Times reports that Trump Jr. was told in an email ahead of his meeting with the Russian lawyer that the compromising information about Clinton was part of a Russian government effort to help his father's campaign, according to three people with knowledge of the email.

Trump Jr.'s attorney responds to NYT

"In my view, this is much ado about nothing. During this busy period, Robert Goldstone contacted Don Jr. in an email and suggested that people had information concerning alleged wrongdoing by Democratic Party front-runner, Hillary Clinton, in her dealings with Russia," Alan Futerfas, Trump Jr.'s attorney, tells The Times in an email. Goldstone is a music publicist who worked on the 2013 Miss Universe pageant with the Trump family.

"Don Jr.'s takeaway from this communication was that someone had information potentially helpful to the campaign and it was coming from someone he knew. Don Jr. had no knowledge as to what specific information, if any, would be discussed."

The Russian lawyer speaks to NBC

Speaking to NBC's "Today" show, Natalia Veselnitskaya, the Russian lawyer at the Trump Tower meeting, denies that she is connected to the Russian government

Trump Jr. tweets email exchange

Trump Jr. releases images of his email exchange with Goldstone and offers a statement to accompany the disclosure: "To everyone, in order to be totally transparent, I am releasing the entire email chain of my emails with Rob Goldstone about the meeting on June 9, 2016. The first email on June 3, 2016 was from Rob, who was relating a request from Emin (Agalarov), a person I knew from the 2013 Ms. Universe Pageant near Moscow. Emin and his father (Aras Agalarov) have a very highly respected company in Moscow. The information they suggested they had about Hillary Clinton I thought was Political Opposition Research. I first wanted to just have a phone call but when that didn't work out, they said the woman would be in New York and asked if I would meet. I decided to take the meeting. The woman, as she has said publicly was not a government official. And, as we have said, she had no information to provide and wanted to talk about adoption policy, and the Magnitsky Act. To put this in context, this occurred before the current Russian fever was in vogue. As Rob Goldstone said just today in the press, the entire meeting was 'the most inane nonsense I ever heard. And I was actually agitated by it.'"

Hannity: "So as far as you know, as far as this incident is concerned, this is all of it?"

Trump Jr.: "This is everything. This is everything."

WaPo: Trump helped come up with misleading statement on Trump Jr.'s meeting

In response to The New York Times' reporting that Trump Jr. met with a Russian lawyer during the campaign, the President dictated a misleading statement for his son, The Washington Post reports.

The Post, citing multiple people with knowledge of the situation, said the original plan in response to The Times' reporting was to issue a truthful statement ahead of the story, but then Trump personally decided to have the statement say Trump Jr. had met with Veselnitskaya to discuss adoption of Russian children by people in the US. The Post reports that Trump dictated the statement on July 8 while flying back to Washington from the G20 summit in Hamburg, Germany, aboard Air Force One.

Trump's attorney, Sekulow, said in a statement in response to the Post story, "Apart from being of no consequence, the characterizations are misinformed, inaccurate, and not pertinent."

White House admits Trump "weighed in" on Trump Jr.'s initial statement

White House press secretary Sarah Huckabee Sanders says the President was involved in the initial statement Trump Jr. released on July 8 about the Trump Tower meeting. Sanders called the matter "of no consequence."

"The statement that Don Jr. issued is true," Sanders said. "There's no inaccuracy in the statement. The President weighed in as any father would, based on the limited information that he had."

"There was no followup. It was a disclosed to the proper parties," she said. "The Democrats want to continue to use this as a PR stunt and are doing everything they can to keep this story alive and in the papers every single day. The President, the American people, they voted America first, not Russia first, and that's the focus of our administration."
