Nikki Haley, the U.S. ambassador to the United Nations, said Defense Secretary Jim Mattis has "plenty of options" for addressing North Korea, in light of Pyongyang's latest missile test that launched over Japan and into the Pacific Ocean early Friday.

Haley, in a White House press briefing with reporters Friday, said tough sanctions are in effect against the North Korean regime, and 90 percent of trade has been cut off against North Korea. Haley emphasized the importance of pushing through "as many diplomatic options as we have." But the Pentagon also has options, she said.

Haley briefed reporters alongside National Security Adviser Gen. H.R. McMaster, after the intermediate-range ballistic missile traveled for 19 minutes before landing in the Pacific Ocean, according to South Korea's military. The missile launch is believed to be North Korea's longest yet.

"I have no problem with kicking it to General Mattis because I think he has plenty of options," Haley said.

McMaster also did not rule out military intervention.

"There is a military option," McMaster said.

McMaster's comments contradict those of former chief Trump strategist Steve Bannon, who recently left the White House to rejoin Breitbart News. Bannon, shortly before his departure, told The American Prospect, "There's no military solution" to North Korea.

Military action is precarious because North Korea could easily strike its southern neighbor and kill potentially millions of people in nearby Seoul.

"There is a consensus among all key nations that denuclearization of the peninsula is the only acceptable objective," McMaster said.

Mr. Trump certainly hasn't closed off the possibility of military action in North Korea. In the past, the president has said the U.S. is "locked and loaded," although he has also said military intervention isn't the preferred route.

On Friday, Mr. Trump — asked if he was running out of diplomatic options for dealing with North Korea — said, "No."

Haley said North Korea will be "front and center" at Mr. Trump's first U.N. General Assembly in New York next week.

In Friday's briefing, McMaster was forced to address an early morning tweet from Mr. Trump, after an explosion at a London train station injured at least 22 people. A London police official has called it a "terrorist incident." Mr. Trump tweeted that the, "sick and demented people" were "in the sights of Scotland Yard," prompting questions about whether Mr. Trump divulged sensitive or even classified information from an earlier call with British Prime Minister Theresa May.

McMaster struggled to directly answer the question, eventually saying he thinks the president was merely saying this kind of attack is what the U.K. and U.S. are trying to prevent.

On the domestic front, White House Press Secretary Sarah Huckabee Sanders said the president will assemble a plan for immigration legislation, including how to handle "Dreamers" affected by the Deferred Action for Childhood Arrivals program, in the next seven to 10 days. The Trump administration earlier this month announced it will be ending the program, and has given Congress six months to find a legislative solution. Earlier this week, Senate Minority Leader Chuck Schumer and House Minority Leader Nancy Pelosi said they struck a deal with Trump on DACA and border security that excludes funding for a border wall, although the White House disputed that account.

White House press secretary Sarah Huckabee Sanders said Mr. Trump "is still 100 percent committed to the wall," after House Minority Leader Nancy Pelosi and Senate Minority Leader Chuck Schumer said the president made a deal with them about the Deferred Action for Childhood Arrivals (DACA) program that excludes a border wall.

The White House has pushed back on that message, saying there is no such agreement to exclude a border wall.

Sanders said the president will lay out a plan for a broad immigration bill including DACA in the next seven to 10 days.

"I think what the president was communicating ... Scotland Yard has been a leader as our FBI has been," McMaster said, claiming the president's tweet only meant this kind of attack is what the U.K. and U.S. are trying to prevent.

There was some concern that Mr. Trump was sharing sensitive or even classified information from an ally.
