Mike McCaul, Citizen Servant

W ashington has almost stopped producing a certain kind of elected official: a man (or woman) who arrives with a job to do, does it well, and leaves at the right time in the right way. Representative Mike McCaul, the Texas Republican and chairman emeritus of the House Foreign Affairs Committee, is departing the House after eleven terms. Conservatives who like to grumble about the Capitol’s do-nothing lifers should take note.

McCaul came to Congress in 2005 by way of the courtroom, not the cocktail circuit. He was a federal prosecutor serving as chief of counterterrorism and national security for the Western District of Texas. Before that, he was a deputy to another Texas hero, then–Attorney General John Cornyn. September 11 changed his priorities and his career. He decided to run for Congress on the proposition that the country had just learned how thin the margin is between security and catastrophe and needed to do everything possible to enhance the former. Fortunately, he never lost sight of his mission and spent the next two decades as a widely respected foreign policy and national security leader in the House.

Much of that work was unglamorous, but deadly serious. As chairman of the Homeland Security Committee from 2013–2019, McCaul was an early evangelist for cybersecurity, at a time when many of his colleagues thought “the cloud” was a weather term. He led the investigation into the 2013 Boston Marathon bombing and pushed to expand TSA PreCheck and Global Entry, the sort of legislation that never made a campaign ad and that millions of travelers use without knowing his name. The government’s first job is to keep its citizens safe. McCaul treated that as a duty, not a talking point.

Then came the Foreign Affairs gavel in 2023, at a moment that demanded a steady hand. The disastrous 2021 withdrawal from Afghanistan was still an open wound, and much of Washington wanted to move on. McCaul refused. His committee investigated the collapse in Kabul and the 13 service members killed at Abbey Gate. He demanded accountability that the Biden administration’s after-action reports did not supply. A republic that cannot look squarely at its failures is not likely to correct them.

On Ukraine, Israel, and Taiwan, McCaul made the argument that Reagan Republicans made without embarrassment: that American strength is the cheapest deterrent ever devised, and that global weakness is terribly expensive. He helped shepherd through the House the 2024 supplemental funding package to support Ukraine when the votes were tight. Serious conservatives disagree about the scale and structure of aid to Kyiv, and opponents to the aid package made good points about burden-sharing, industrial capacity, and a Pacific theater that needs more of our attention. But McCaul’s answer was never naïve or simplistic. Early on he saw Moscow, Beijing, Tehran, and Pyongyang as a loosely coordinated bloc of unprincipled and ruthless adversaries who seek to destroy us. And he was 100 percent correct.

The proof is this month’s headlines. When former Senator Lindsey Graham died suddenly in July, shortly after returning from Kyiv with a deal to bring the White House aboard his long-stalled Russia sanctions bill, the measure could have died with him. But McCaul had promised his friend and mentor he would carry it in the House, and he did, introducing the Lindsey Graham Sanctioning Russia and Iran Act of 2026 with Democrat Steny Hoyer and working it through the Rules Committee onto the floor. Multiple House leaders point to McCaul’s bipartisan leadership as the key. On September 16, the House passed the Graham Act 262 to 159; two days later, President Donald Trump signed it into law. The bill authorizes tariffs of up to 100 percent on the top five buyers of Russian oil and gas, tightens sanctions on the Russian officials and banks funding the war, and extends sanctions on Iran. It was a huge victory for all who support a free and peaceful Ukraine and for everyone who cares about democracy, liberty, and the rule of law in our world.

With Trump’s widespread and unconstitutional use of tariffs increasing the tax burden on ordinary Americans, free traders have reason for unease about handing him such broad authority, and most House Democrats voted no on the sanctions act on those grounds. But the 262-vote tally made it Congress’s first bipartisan Ukraine legislation since April 2024, assembled by a man with no gavel to wield and an exit date already on the calendar.

America’s adversaries noticed McCaul, too. After a 2023 visit to Taiwan, the Chinese Communist Party sanctioned McCaul for meddling in its “internal affairs.” McCaul (and others like former U.S. Senator Sam Brownback) wore the designation as an honor, and rightfully so. When the world’s largest dictatorship takes the trouble to blacklist an American politician, you can be sure he is doing something correctly.

McCaul’s CHIPS for America Act drew more conservative quibbling, and fairly so. Corporate subsidies are not a method most conservatives agree on. Yet the premise behind the bill was neither socialist nor silly: The most advanced semiconductors on earth are made on an island a hundred miles from a hostile superpower that has promised to take it by force as soon as possible. Those chips power our weapons, our economy, and our future, and a nation that cannot make them is a nation that can be blackmailed. McCaul understood that and helped guide the bill to success.

What most distinguishes Mike McCaul, however, is how he is leaving. House Republicans limit the tenure of committee chairmen, and he was term-limited out of both committee positions he had earned. Plenty of members, when denied their perch, discover an urgent new love of the institution and hang on for another decade of committee seniority and cable news hits. McCaul instead announced in September 2025 that he would not seek reelection. He said that some members cannot let go and Congress is weaker as a result. He preferred to depart on his own terms. He treated the office as a trust to be discharged, not an estate to be defended.

Our Founders admired the citizens who take up the sword or the gavel when the republic needs them and lay it down again when it does not. They worried that the country’s institutions would fill up with people who mistook the office for the self. McCaul understood the difference.

He says he is looking for a new challenge in national security and foreign policy, and one hopes this administration, or a future one, finds a significant role for him. The GOP’s foreign-policy bench is thinner than it should be, and the world is more dangerous than it has been in a generation. Congress will have to relearn how to function without one of its most serious and respected leaders. Our nation needs more like him.
