Washington (CNN) President Donald Trump said Friday he was personally crafting the answers to special counsel Robert Mueller and denied he was agitated by the state of the probe.

"I write the answers. My lawyers don't write answers. I write answers. I was asked a series of questions. I've answered them very easily -- very easily. I'm sure they're tripped up, because you know they like to catch people," Trump told reporters gathered for a bill signing.

He said he hasn't submitted them, but that he's just finished them. CNN has previously reported Trump has met with his lawyers several times this week to go over Mueller's questions.

Asked if anything specific triggered his recent angry tweets about Mueller, Trump said: "No, not at all. I'm very happy. I'm very happy with the White House."

"I'm not agitated. It's a hoax. The whole thing is a hoax. There was no collusion," he said of Mueller's investigation into Russian election meddling and potential obstruction of justice.
