Seeking to derail North Korea’s drive for nuclear weapons, senators set aside their partisan differences on Wednesday to support legislation aimed at starving Pyongyang of the money it needs to build an atomic arsenal.

The Senate is scheduled to vote later Wednesday on a bill to impose more stringent sanctions on North Korea. But there appears to be no opposition after a series of floor speeches by Republicans and Democrats who repeatedly denounced Pyongyang for flouting international law by pursuing nuclear weapons.

Sen. Bob Menendez, D-N.J., said for too long North Korea has been dismissed as a strange country run by irrational leaders.

“It’s time to take North Korea seriously,” Menendez said.

The Senate bill, authored by Menendez and Sen. Cory Gardner, R-Colo., targets North Korea’s ability to finance the development of miniaturized nuclear warheads and the long-range missiles required to deliver them. The legislation also authorizes $50 million over the next five years to transmit radio broadcasts into North Korea, purchase communications equipment, and support humanitarian assistance programs.

The legislation comes in the wake of Pyongyang’s recent satellite launch and technical advances that U.S. intelligence agencies said the reclusive Asian nation is making in its nuclear weapons program.

The House overwhelmingly approved North Korean sanctions legislation last month. While there are differences in the two bills, Sen. Bob Corker, the chairman of the Senate Foreign Relations Committee, said he does not expect any difficulty in producing a final measure.

The House sent the Senate a bill that was very strong and “we’ve been able to improve it,” said Corker, a Tennessee Republican. “I think they’ll be happy with those improvements.”

GOP senators and presidential candidates Ted Cruz of Texas and Marco Rubio of Florida were to return to Washington from campaigning to vote on the bill.

North Korea on Sunday launched a long-range rocket carrying an Earth observation satellite into space. The launch, which came about a month after the country’s fourth nuclear test, was quickly condemned by world leaders as a potential threat to regional and global security.

Washington, Seoul and others consider the launch a banned test of missile technology. That assessment is based on Pyongyang’s efforts to manufacture nuclear-tipped missiles capable of striking the U.S. mainland and that the technology used to launch a rocket carrying a satellite into space can be applied to fire a long-range missile.

In the annual assessment of global threats delivered to Congress on Tuesday, Director of National Intelligence James R. Clapper said North Korea has expanded a uranium enrichment facility and restarted a plutonium reactor that could start recovering material for nuclear weapons in weeks or months.

Both findings will deepen concern that North Korea is not only making technical advances in its nuclear weapons program, but is working to expand what is thought to be a small nuclear arsenal. U.S.-based experts have estimated that North Korea may have about 10 bombs, but that could grow to between 20 and 100 by 2020.

Clapper said that Pyongyang has not flight-tested a long-range, nuclear-armed missile but is committed to its development.

Underscoring the difficulty of understanding North Korea’s actual intentions, Clapper said the U.S. does not know whether North Korea would use nuclear weapons for defensive or retaliatory purposes.

But Clapper said U.S. intelligence has determined Pyongyang does want nuclear capabilities for purposes of deterrence, international prestige, and coercive diplomacy.

North Korea already faces wide-ranging sanctions from the United States and under existing U.N. resolutions is prohibited from trading in weapons and importing luxury goods.

The new legislation seeks additional sanctions — both mandatory and at the discretion of the president — against the government of North Korean leader Kim Jong Un and those who assist it.

It would require the investigation and punishment of those who knowingly import into North Korea any goods or technology related to weapons of mass destruction; those who engage in human rights abuses, money laundering and counterfeiting that supports the Kim regime; and those who engage in “cyber-terrorism.”

The bill also bans foreign assistance to any country that provides lethal military equipment to North Korea, and targets Pyongyang’s trade in key industrial commodities.
