For five days, Iran and Israel have been trading airstrikes in escalating conflict. And now, Donald Trump has signaled that he may get the United States involved.1
So Alexandria has announced she will be signing onto Rep. Thomas Massie’s bipartisan War Powers Resolution, to block U.S. involvement in this war without authorization from Congress:

According to the Constitution, the right to declare war belongs to Congress — and yet many global acts of aggression have never once been voted on by Congress.
In some cases, we've even acted without the backing of the United Nations.
The people who tell you we do have war money, but don’t have healthcare money, infrastructure money, or Green New Deal money are playing games with you.
In solidarity,
Team AOC
