President Donald Trump took to Twitter in the early hours of Wednesday to support his son, who appeared on Sean Hannity’s Fox News talk show the previous night to discuss the emails between the Trump campaign and a Russian lawyer. The emails show the campaign working to obtain information about Hillary Clinton during the 2016 presidential election.

“My son Donald did a good job last night,” Trump posted on his Twitter page. “He was open, transparent and innocent. This is the greatest Witch Hunt in political history. Sad!”

Around 15 minutes later, Trump posted again to decry the “fake media” that cites anonymous sources.

“Remember, when you hear the words “sources say” from the Fake Media, often times those sources are made up and do not exist,” he said.

Trump’s son is at the heart of a scandal that erupted on Tuesday, after he posted emails on his Twitter page that showed him speaking to Rob Goldstone, a British-born publicist, about information that could help the Trump campaign in the 2016 election.

“The Crown prosecutor of Russia met with his father Aras this morning and in their meeting offered to provide the Trump campaign with some official documents and information that would incriminate Hillary and her dealings with Russia and would be very useful to your father,” Goldstone said in his email. “This is obviously very high level and sensitive information but is part of Russia and its government’s support for Mr. Trump - helped along by Aras and Emin.”

In his interview with Hannity, Trump Jr. maintained the line that campaigns regularly seek out opposition research, he came away without information on Clinton, and that he did not inform his father of the meeting.

“In retrospect, I probably would’ve done things a little differently,” Trump Jr. said in the interview, before claiming that the interview was “a waste of 20 minutes” as the meeting with the Russian lawyer, Natalia Veselnitskaya, “went nowhere.”

On Tuesday, Trump issued a single-line statement regarding his son: “My son is a high-quality person and I applaud his transparency.”
