Donald Trump says he has finished answering questions into alleged Russian meddling during the 2016 presidential campaign.
The US leader told reporters he had personally answered the questions "very easily", but that they had yet to be submitted to Robert Mueller's team, according to BBC report.
Mueller has been looking into allegations of collusion between Mr Trump's campaign and Russia since 2017.
Trump strongly denies any collusion, calling the probe "a witch hunt".
On Thursday, he took to Twitter to describe Mueller as "conflicted", called the investigation "absolutely nuts", adding that those involved in the long-running probe "are a disgrace to our nation".
The tweets came a week after he forced the resignation of Attorney General Jeff Sessions, replacing him with Matthew Whitaker, who now has the power to sack Mueller or end the investigation.
Speaking to reporters on Friday, he said the investigation had wasted "millions and millions of dollars" and "should never have taken place".
Trump also suggested the people who wrote the questions he agreed to answer "probably have bad intentions".
"I'm sure they're tricked-up because, you know, they like to catch people," Trump said, after making it clear he had written the answers to the questions.
