Donald Trump held press conference promising more dirt on Clinton hours after Donald Trump Jr's Russia emails

In a series of emails sent in June 2016, President Trump's eldest son discussed setting up a meeting with a Kremlin-connected lawyer

Hours after Donald Trump Jr confirmed a meeting with a Russian lawyer to discuss information on Hillary Clinton, his father promised to make a speech with new information about his former rival for the US presidency.

“I think you’re going to find it very informative and very very interesting,” the US leader said, adding that it would likely take place next week.

"We are going to be discussing all of the things that have taken place with the Clintons," he said.

His comments came after his son released emails relating to his previously undisclosed meeting last summer with Russian lawyer Natalia Veselnitskaya, who has been linked to the Kremlin.

He said "I love it" to what he had been told was an attempt by the Russian government to undermine Hillary Clinton's presidential election campaign.

Mr Trump Jr has denied telling his father about the meeting, claiming “there was nothing to tell” and that the meeting was a “wasted 20 minutes”.

However, he has said that with hindsight, he “probably would have done things a little differently".

He posted the email exchange on Twitter this week in anticipation of a New York Times story on the subject that was scheduled to be published.

The President has praised the transparency shown by his eldest son and described him as a “high quality person” in a statement read out by White House spokeswoman Sarah Huckabee Sanders.

His defence of his son comes despite the fact that the emails increase the pressure on the White House over a number of investigations into potential ties between the Trump team and Russia.

Democrats have jumped on the revelations, calling the emails "explosive".

A number of Democrats also claimed that the messages prove there was collusion between the Trump campaign and Russia as part of attempts by Moscow to meddle in the 2016 presidential election - something the White House has repeatedly denied.
