Lawmakers, US allies seek assurance that Trump won't rashly launch nuclear strike



A decades-old presidential authority to use nuclear weapons is suddenly coming into question as US allies and some lawmakers from both parties want the Trump administration to assure them that President Donald Trump cannot rashly launch a nuclear strike, according to multiple sources.
The potential that Trump could use existing law to authorize the deployment of a nuclear weapon on his own is becoming the subject of frequent conversation -- and bipartisan anxiety -- on Capitol Hill. Senate Foreign Relations Committee Chairman Bob Corker will hold a hearing Tuesday on the authority of the President to maintain sole authority to launch nuclear weapons.
