Sen. Rand Paul (R-KY) blasted the Trump administration Sunday for its ongoing military strikes on suspected drug traffickers in the Caribbean, labeling them as “extrajudicial killings” that he argued were similar to how the Iranian or Chinese governments operate.

“The drug or the crime war has typically been something we do through law enforcement, and so far they have alleged that these people are drug dealers,” Paul said, appearing on Fox News Sunday.

“No one's said their name, no one's said what evidence, no one's said whether they're armed, and we've had no evidence presented. So at this point, I would call them extrajudicial killings. This is akin to what China does, to what Iran does with drug dealers, they summarily execute people without presenting evidence to the public, so it's wrong.”

President Donald Trump has authorized at least ten strikes on suspected drug-carrying sea vessels since September, killing at least 43 people that his administration has labeled as “narco-terrorists.” The strikes have received widespread bi-partisan condemnation for potentially being a violation of international law, with the most-recent strike occurring late Thursday night into Friday morning, killing six.

Trump’s authority to authorize the strikes has also been questioned by critics, who point to Congress’ sole authority to approve declarations of war. Congress has not approved the strikes, and, according to Paul, have not even been briefed on the operations, or the evidence – should any exist – that those targeted were actually engaged in drug trafficking.

“We haven't had a briefing; to be clear, we've gotten no information, I've been invited to no briefing, but a briefing is not enough to overcome the Constitution,” Paul said. “The Constitution says that when you go to war, Congress has to vote on it, and during a war, there's a lower rules for engagement, and people do sometimes get killed without due process.”
