President Donald Trump said he had "very easily" completed his written answers for Special Counsel Robert Mueller's investigation into Russia's role in the 2016 Presidential election.
But Mr Trump said he had not yet submitted them to Mr Mueller's office.
Speaking to reporters at the White House, Mr Trump said he wrote the answers to the questions himself.
"My lawyers don't write answers. I write answers. I was asked a series of questions. I've answered them very easily," said Mr Trump.
While Mr Trump did not specify when his legal team would give Mr Mueller his written responses, a person familiar with the matter said it is likely they would be submitted next week.
Peter Carr, a spokesman for Mr Mueller, declined to comment.
The president said some questions were "tricked-up" and suggested that some of them were designed to result in perjury charges.
He said: "You have to always be careful when you answer with people that probably have bad intentions."
The inner workings of the Mueller investigation are a total mess. They have found no collusion and have gone absolutely nuts. They are screaming and shouting at people, horribly threatening them to come up with the answers they want. They are a disgrace to our Nation and don’t...

Mr Mueller is investigating whether members of Mr Trump's campaign conspired with Russia in the 2016 presidential election and whether the president has unlawfully sought to obstruct the probe.
Mr Trump's team of lawyers agreed to have the president submit written answers to questions relating to Russia's role in the election.
But it is still possible Mr Mueller may press Mr Trump to answer questions on potential obstruction at some point and whether the President will eventually sit for an interview.
Tensions have risen over the probe since Mr Trump ousted Jeff Sessions as US attorney general last week.
President Trump again called the investigation a "witch hunt" and said there was no collusion.
Russia has denied any interference in the 2016 presidential election.
