Washington (CNN) President Donald Trump believes the "greatest immediate threat" to the US is North Korea and its nuclear program, a senior administration official told reporters. Trump has already called on China to take action to rein in North Korea, over which China has considerable influence and leverage, the official said. "You gotta work on North Korea," Trump told a Chinese official on February 27, the senior administration official said, apparently pointing to a brief meeting at the White House between Trump and Chinese State Councilor Yang Jiechi, the highest-ranking Chinese official Trump has met with since taking office. North Korea has successfully developed nuclear weapons, but still lacks a delivery method, the official said. Still, the US administration is concerned that North Korea could purchase a delivery method."You gotta work on North Korea," Trump told a Chinese officialNorth Korea has successfully developed nuclear weapons
The question for _, though, has been, "Is he crazy or is he smart and strategic?".

(CNN) Ret. Vice Adm. Bob Harward turned down President Donald Trump's offer to be national security adviser Thursday, depriving the administration of a top candidate for a critical foreign policy post days after Trump fired Michael Flynn. Trump has since named Ret. Lt. Gen. Joseph Keith Kellogg, who worked under Flynn until the latter was asked to resign, as the acting national security adviser. Asked if there was a candidate for national security adviser in sight, a White House official told CNN, "Not that I'm aware of." "Since retiring, I have the opportunity to address financial and family issues that would have been challenging in this position," Harward said in a statement. "Like all service members understand, and live, this job requires 24 hours a day, 7 days a week focus and commitment to do it right. I currently could not make that commitment. My thoughts and prayers are with those that carry such heavy burdens and responsibility for taking care of our country's national security concerns. God bless this great country of ours."A friend of Harward's said he was reluctant to take the job because the White House seems so chaoticEarlier this week, Trump fired Michael Flynn as national security adviser
