Trump’s Drug War is igniting an unusual rift within the Republican Party, as a growing number of GOP lawmakers—many of whom have rarely challenged the former president—now demand congressional oversight and legal clarity for his expanding military campaign against drug cartels.
What Is Trump’s Drug War?
Since early September 2025, the Trump administration has launched at least 10 lethal military strikes targeting vessels allegedly trafficking narcotics in the Caribbean and Pacific. More than 10,000 U.S. troops and military aircraft have been deployed across Latin America under the banner of combating “narcoterrorists”—a term Defense Secretary Pete Hegseth has used to justify the offensive.
President Trump has repeatedly stated he will not seek congressional approval for these operations, asserting executive authority as commander in chief. “I think we’re just going to kill people that are bringing drugs into our country, OK? They are going to be, like, dead,” Trump told reporters at the White House on October 24.
Rare Republican Pushback Emerges
While most Republicans continue to back Trump’s aggressive stance, a notable faction—including Senators Mike Rounds (S.D.), Susan Collins (Maine), Thom Tillis (N.C.), and Todd Young (Ind.)—is calling for transparency, legal justification, and formal congressional involvement.
“We have oversight responsibilities, and we expect to get our questions answered,” said Sen. Rounds, a member of the Armed Services Committee.
Sen. Collins went further, arguing that drug interdiction should remain a law enforcement mission. “Historically, the interception of drug-running boats has been the job of the Coast Guard… To me, that’s what we should be using,” she said.
Upcoming Senate Vote Tests GOP Unity
Next week, the Senate will consider a bipartisan resolution that would prohibit U.S. military strikes “within or against” Venezuela without explicit congressional authorization. Sponsored by Sens. Tim Kaine (D-Va.) and Rand Paul (R-Ky.), the measure faces steep odds—it would need at least four Republican votes to advance, and President Trump is expected to veto it if it passes.
So far, only two Republicans—Sens. Lisa Murkowski (Alaska) and Rand Paul—have openly opposed the military campaign. Paul, a longtime non-interventionist, warned of potential escalation: “An offensive war for regime change [in Venezuela] would be a mistake.”
Legal and Intelligence Concerns Mount
Behind closed doors, GOP and Democratic senators have pressed Pentagon officials for the legal basis of the strikes. In a classified briefing, Pentagon lawyer Earl Matthews cited Trump’s designation of certain cartels as “foreign terrorist organizations” as justification for unilateral military action.
However, senators from both parties expressed skepticism. Matthews refused to provide a written legal rationale, fueling frustration among lawmakers who say they’re learning about operations through Trump’s social media posts—not official briefings.
Supporters Defend the Campaign
Not all Republicans are wavering. Sen. Jim Risch (Idaho), chairman of the Foreign Relations Committee, dismissed calls for oversight: “The president of the United States saved lives, lots of lives. We should be commending him.”
Rep. Brian Mast (R-Fla.), chair of the House Foreign Affairs Committee, called the cartels “terrorists” and said strikes were based on “credible intelligence from numerous agencies.”
Constitutional Tensions Rise
The Constitution grants Congress the sole power to declare war—a responsibility largely dormant since World War II. While modern presidents have frequently acted unilaterally under broad authorizations, Trump’s refusal to even consult Congress marks a new flashpoint.
“Congress alone is entrusted with decisions of war and peace,” Sen. Young emphasized in a public statement, reflecting a growing unease even among loyalists.
