Senators who were briefed at the White House on Wednesday about the situation with North Korea said they learned “very little” during the all-hands meeting — with some claiming it lacked “even straight answers” about President Trump’s ongoing plans.

“There was very little, if anything new,” Sen. Richard Blumenthal (D-Conn.) told The Washington Post.

“I remain mystified about why the entire Senate had to be taken over to the White House rather than conducting it here,” he said.

One Republican lawmaker, who chose to remain anonymous, claimed they weren’t updated on what the current policy was regarding the Hermit Kingdom — nor the US military’s testing of intercontinental ballistic missiles that took place on Wednesday morning.

“Several senators asked specifically, ‘What is the policy?’ and the briefers gave us very, very few details,” the senator said.

The meeting — considered a major departure from normal procedure — was attended by nearly every US senator after being ordered by Senate Majority Leader Mitch McConnell.

It came as tensions continued to escalate in the region.

President Trump recently redirected the USS Carl Vinson aircraft carrier strike group towards the Korean Peninsula following the North’s failed missile test last week. He also authorized the launch of an unarmed ICBM from California’s Vandenberg Air Force Base early Wednesday.

At the beginning of the White House session, he and Vice President Pence gave a brief address before Secretary of State Rex Tillerson, Defense Secretary Jim Mattis, Director of National Intelligence Daniel Coats and Gen. Joseph F. Dunford Jr., chairman of the Joint Chiefs of Staff, took turns speaking to the senators.

They reportedly described how North Korea’s nuclear weapons program was “an urgent national security threat and top foreign policy priority,” adding that Trump hoped to impose economic sanctions and find a “diplomatic” solution with US allies.

The president’s goal, the group said, was to ultimately “convince the regime to de-escalate and return to a path of dialogue” — in the attempt to bring peace to the Korean Peninsula.

“We remain open to negotiations to towards that goal,” they reportedly told the senators. “However we remain prepared to defend ourselves and our allies.”

While some senators described Wednesday’s briefing as “sobering,” most griped about it being redundant.

“I didn’t hear anything new because I have been heavily briefed before,” Sen. John McCain told CNN. “It’s a very serious situation, just as I had (thought) before I went there.”

The anonymous lawmaker who spoke to the Post added, “The basic gist of it at the beginning was that we’re going to get more aggressive…We’ve reached a point where things are getting pretty dire and getting to the point where we’ve got to get more aggressive.

“From then on, what we all wanted to know is, What does that mean?” the senator said. “What is it that we should be looking for as the trigger that something is about to happen and that we’d end up taking some kind of kinetic action? That’s where things got a little elliptical.”
