Donald Trump Jr. on Monday denied that he changed his story about why he had a sitdown with a shady Russian lawyer who was dishing dirt on Hillary Clinton.

“No inconsistency in statements, meeting ended up being primarily about adoptions. In response to further Q’s I simply provided more details,” Trump Jr. tweeted about a Sunday New York Times article that reported the shifting explanations.

The president’s eldest son met on June 9, 2016, at Trump Tower with Natalia Veselnitskaya after he was told by a pal that the Kremlin-connected attorney was offering damaging information about Clinton.

His first statement Saturday didn’t mention that the Russian had offered information about the former first lady.

“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,” he said.

But on Sunday, Trump Jr. admitted that Veselnitskaya had offered him dirt on Clinton, but that her statements were “vague, ambiguous and made no sense” and that it “became clear that she had no meaningful information.”

Trump Jr. also defended his decision to go after the negative info in a tweet posted Monday.

“Obviously I’m the first person on a campaign to ever take a meeting to hear info about an opponent… went nowhere but had to listen,” he sarcastically tweeted.

Also Monday, Trump counselor Kellyanne Conway told “Good Morning America” that “no information was received that was meaningful or helpful” during Trump Jr.’s meeting.

“There’s no evidence of collusion” between Team Trump and Russia in the campaign, Conway added.

ABC’s George Stephanopoulos fired back that Trump Jr. was clearly expecting to get damaging information.

“Isn’t that at minimum an attempt at collusion?” Stephanopoulos asked.

“Are you saying there’s evidence of collusion because everybody is trying to convert wishful thinking into hard evidence and haven’t been able to do that,” Conway replied.

Stephanopoulos also asked her about her previous statements that there were no meetings between Trump associates and the Russians.

“Why did the administration allow those denials to stand for so many months?” he asked.

“Some of the disclosure forms have been amended since that time to reflect other meetings,” including the meeting Trump Jr., Kushner and Manafort had with Veselnitskaya, she said.

Conway also went on CNN to repeat her denials that collusion had taken place.

“Don Jr. has very explicitly stated he didn’t even know the name of the person with whom he was meeting,” she said. “He agreed to the meeting based on a contact from the Miss Universe Pageant.”

“They get into the meeting and it quickly turns into a pretext for Russian adoption, according to his statements, that the comments this woman is making about any type of information on Hillary Clinton were vague. They were meaningless.”

But host Chris Cuomo pointed out that despite his denials, “He changed his story twice. You talked about being in a court of law — not good when you change your story,” Cuomo said.

“There are big implications when you change your story like this. Whether or not it was good information, Kellyanne, doesn’t mean it was a smart move to take a meeting with a Russian-connected person who was going to give you negative information about your opponent. That could create huge legal issues. You know that,” he added.
