@Builder,
Some Democratic lawmakers on Friday sought justification from the Biden administration for Thursday's airstrikes in Syria, marking the first significant test of President Biden's military approach.
"The American people deserve to hear the Administration's rationale for these strikes and its legal justification for acting without coming to Congress," Virginia Sen. Tim Kaine said in a statement. "Offensive military action without congressional approval is not constitutional absent extraordinary circumstances. Congress must be fully briefed on this matter expeditiously."
The airstrikes, which targeted Iranian-backed militia groups in Eastern Syria, came in response to recent attacks and threats against Americans and coalition personnel in Iraq, the Department of Defense said.
Biden, traveling in Texas, was asked Friday what message he intended to send Iran through the airstrikes. He answered, "You can't act with impunity."
White House spokeswoman Jen Psaki spoke earlier in the day in more detail about the matter, telling reporters traveling on Air Force One that the "president is sending an unambiguous message that he's going to act to protect Americans, and
when threats are posed, he has the right to take an action at the time, and in the manner of his choosing." (end quote)
I'd definitely say that the highlighted section (my bolds) indicates total unilateral action is Biden's modus operandi at this stage.
Let's hope that his own "party" reels him in, post-haste, to avoid escalation.
