(CNSNews.com) - National Security Adviser H.R. McMaster said on Sunday he doesn't have time to worry about Special Counsel Robert Mueller's investigation, which on Friday produced a guilty plea from Michael Flynn, McMaster's predecessor.
Chris Wallace, the host of "Fox News Sunday," asked McMaster if he's been reassuring U.S. allies "that President Trump is firmly in charge, and his presidency is not in trouble."
"No, I don't think our allies need any reassurance," McMaster said.
“In fact, what we're doing is continuing to work with them on all the key challenges we face today, from North Korea, to the defeat of ISIS across the greater Middle East, the ongoing efforts in Afghanistan, Pakistan. We're working with our Latin American partners very closely on the issue of Venezuela.
"And so, we're -- we haven't missed a beat, really, and the topic doesn't even come up."
McMaster said alleged collusion with the Russians during the campaign "is not our focus on the National Security Council, obviously.
"So what we're focused on are, you know, the key issues that we have to confront today to protect the American people, advance our prosperity.
“The priorities that the president's given us to move as quickly as we can to resolve this crisis with North Korea, a regime that's threatening the world, and to do everything we can to, as we defeat ISIS in the greater Middle East, make sure conditions are set so that ISIS doesn't return.
“And also, so that we address the problem of Iranian influence across the region, which is driving a lot of this humanitarian and political crisis in the Middle East.”
Wallace refuse to give up, asking McMaster: "On a personal level, though, what are your thoughts about Gen. Flynn, fellow soldier who served in the military for 33 years, pleading guilty to lying to the FBI?"
"Well, Chris, I -- you know, my thoughts are on what we have to do for the country," McMaster replied.
"I don't -- I don't really have a lot of spare time to think about other topics, other than our greatest national security challenges."
