He repeated that he had not known about the meeting in advance.
"Fake News reporting, a complete fabrication, that I am concerned about the meeting my wonderful son, Donald, had in Trump Tower", he said in tweet early Sunday. "This was a meeting to get information on an opponent, totally legal and done all the time in politics - and it went nowhere", he wrote.
'The Fake News hates me saying that they are the Enemy of the People only because they know it's TRUE, ' he tweeted.
Mueller is in the midst of a 15-month investigation of Russian meddling in the 2016 USA presidential election, Trump campaign ties to Russia and whether Trump, as president, obstructed justice by trying to thwart the investigation. He campaigned for a Republican candidate facing a tough race Tuesday for a seat in the House of Representatives, the last special election before the nationwide November 6 voting, when the entire 435-member House is being contested and a third of the 100-member Senate.
Email released by Donald Jr. himself showed he had been keen on the meeting because his father's campaign was purportedly being offered potentially damaging information on Clinton.

At the time, in July 2017, Trump offered a similar comment to the one he made on Sunday, dismissing the meeting with a Russian lawyer promising dirt on his political opponent as no big deal. Last week, however, he adopted his lawyers' tactics and insisted "collusion is not a crime".More news: 'That's enough': Robert Redford announces his retirement from acting

He has called the ongoing investigations in the USA "the greatest political witch hunt in history".
He said: "You have to look at what laws, rules, regulations, statutes are purportedly violated here".
Some have argued that the Trump Tower meeting involved the illegal exchange of a "thing of value" with foreign nationals for campaign finance purposes, although the extent to which information sharing can legally constitute a "thing of value" is unsettled.
Lawyers described the statement as "short but accurate", according to The Post. 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.
It is common for United States politicians to research their opponents during a campaign.
Trump has repeatedly expressed his desire to shut down the Mueller investigation.
"I think there's plenty of evidence of collusion or conspiracy in plain sight". Last week, Trump's national security team said Russian Federation was behind "pervasive" attempts to interfere in November 2018 congressional elections. I would say that Robert Mueller will reveal the answer to that question, but given that the most damning information in this saga has come from POTUShitforbrains and his failson namesake, we can probably expect one of the Donald's to tweet the truth in the coming weeks as Mueller's probe continues to close in on a president who openly solicited the aid of a foreign adversary.
