President Donald Trump said he is not considering firing special counsel Robert Mueller, who is leading an investigation into any links between his campaign and Russia.
Mr Trump has dismissed Mr Mueller's probe as a "witch hunt" and there has been speculation he might try to remove him.
But Mr Trump told reporters at his New Jersey golf course: "I haven’t given it any thought. I’ve been reading about it from you people. You say, ‘Oh, I’m going to dismiss him.’ No, I’m not dismissing anybody."
Mr Trump said he supported investigations, including in Congress, into Russia's meddling in last year's election.
He said: "I want them to get on with the task."
Addressing a wide range of issues Mr Trump also responded to Vladimir Putin's recent decision to expel 755 US diplomats.
Mr Trump said: "I want to thank him because we’re trying to cut down our payroll and as far as I’m concerned I’m very thankful that he let go of a large number of people because now we have a smaller payroll.
"There’s no real reason for them to go back. I greatly appreciate the fact that we’ve been able to cut our payroll of the United States. We’re going to save a lot of money."
The president also said he was "surprised" by the revelation that FBI agents raided the home of Paul Manafort, his former campaign chairman, as part of Mr Mueller's probe.
Mr Trump said: "Whether or not it was appropriate you’d have to ask them. I’ve always found Paul Manafort to be a very decent man.
"He’s like a lot of other people, probably makes consultant fees from all over the place, who knows, I don’t know, but I thought it was pretty tough stuff to wake him up, perhaps his family was there. I think that’s pretty tough stuff."
