Maine U.S. Sen. Susan Collins is co-sponsoring legislation that would prevent President Trump from taking the United States out of NATO without Senate approval.
“It would remove the ability of the president to unilaterally withdraw us from NATO," Collins says. "It says there would have to be a two-thirds vote of the Senate.”
Collins, a Republican, says members of NATO are staunch allies of the United States and President Trump should realize the United States is stronger because of the alliance.
“Now, I will freely admit there are some constitutional issues that could be raised about this bill," she says. "But it is important for us to send a signal that we stand behind our NATO allies.”
Collins says the proposal might run afoul of the constitutional powers of the president.
