President Donald Trump says he doesn’t feel bad ordering U.S. strikes against suspected drug vessels, saying he is “saving” lives.

“The only way you can’t feel bad about it ... is that you realize that every time you see that happen, you’re saving 25,000 lives,” the president said of the series of strikes off of Venezuela.

He insisted of such strikes, “We have legal authority. We’re allowed to do that.”

Trump said similar strikes could eventually come on land, in which case his administration may subsequently go to Congress for authorization.

Lawmakers from both parties have increasingly expressed concerns about Trump ordering a series of strikes against suspected drug vessels without providing Congress many details.

Appearing alongside Trump, Secretary of State Marco Rubio, a former senator, defended such strikes, saying, “If people want to stop seeing drug boats blow up, stop sending drugs to the United States.”
