Democrats are trying to stop Trump from launching nuclear weapons without congressional approval

Now that President Trump has the nuclear codes in his hands, two Democratic lawmakers are hoping to make it a little harder for him to actually use them. On Tuesday, Sen. Ed Markey (D-Mass.) and Rep. Ted Lieu (D-Calif.) reintroduced a bill that would prevent Trump from launching a nuclear strike if Congress had not declared war. As it stands now, the president holds the right to launch a preemptive nuclear strike, a policy both Markey and Lieu oppose no matter who the president may be.

Markey and Lieu first tried to introduce this bill in September, after Trump suggested at a presidential debate that he couldn't "take anything off the table" when it came to nuclear weapons, including first strike. But now that Trump has actually been sworn into office, Markey and Lieu say this bill is more pressing than ever.

"It is a frightening reality that the U.S. now has a commander-in-chief who has demonstrated ignorance of the nuclear triad, stated his desire to be 'unpredictable' with nuclear weapons, and as president-elect was making sweeping statements about U.S. nuclear policy over Twitter," Lieu said in a statement. He urged Congress to pass a "system of checks and balances" to be "applied to the potentially civilization-ending threat of nuclear war."
