WASHINGTON — The overwhelming vote Tuesday by the GOP-controlled House to impose new Russia sanctions sends a strong and defiant message to President Donald Trump — all the more remarkable because it came from his own party.

The 419-3 vote not only bucked a tradition of leaving foreign policy matters to the president, it marked the most significant example to date of the current Republican Congress standing up to its often unpredictable and disruptive standard-bearer.

The new bill orders up a regimen of tougher sanctions in reprisal for Russia’s meddling in the 2016 U.S. elections. More importantly, it prevents Trump from unilaterally easing the punitive measures, something he has hinted he might do.

Congress “is uncomfortable with any rapprochement with Moscow without getting some things for it,” Rep. Adam Kinzinger, R-Ill., said ahead of the vote. “We’re sending a message to Moscow. But if the president had any intention of trying to give Vladimir Putin what he wants on certain areas, I think he’ll think twice about it.”

A similar bill was approved earlier by the Senate on a 98-2 vote. Tuesday’s House version wrapped in sanctions against North Korea, so it must return to the Senate, where it is expected to pass. The bill also includes sanctions against Iran, making it harder for Trump to veto.

Several foreign policy professionals said they normally oppose congressionally mandated sanctions because they are harder to unwind and interfere with the smooth and intricate flow of international diplomacy.

But they said Trump’s unorthodox approaches and his apparent affinity for Putin have given sufficient cause for Congress to act on its own.

“It is not unusual that Congress wants to tie a president’s hands, but it is highly unusual that the president’s own party is tying his hands,” said Jeffrey Mankoff, a Russia scholar at the Center for Strategic and International Studies and former adviser on Russia to the State Department. “It tells me that there is a lot of suspicion about Trump, his family and ties to Russia.”

Trump has repeatedly cast doubt on U.S. intelligence conclusions that Russia meddled in the 2016 campaign, has spoken glowingly about Putin and, at least publicly, did not use the recent meeting of the Group of 20 industrialized nations to rebuke the Russian president for his alleged misdeeds.

Traditionally, foreign policy experts, historians and a number of the United States’ allies abroad have been loath to see Congress step into matters of international diplomacy. The single voice of a chief executive can respond in ways that would take the 535 voices of the U.S. Congress much longer to accomplish, if ever.

And when sanctions against a country or entities in other countries are enshrined in U.S. law, it takes another law to undo them.

In 1974, over the objections of President Gerald Ford, Congress voted unanimously to punish the then-Soviet Union with trade sanctions and embargoes in response to human rights abuses, particularly its refusal to allow Jewish citizens to emigrate. Eventually, under President Mikhail Gorbachev in the late 1980s, Soviet Jews did begin to leave in large waves.

The Soviet Union fell in 1991, and yet the law, known as the Jackson-Vanik amendment, remained on the books until 2012.

Diplomats say it was a constant irritant in negotiations over the years with the Russians, who found it condescending, not to mention outdated and unnecessary.

In a curious twist, the Jackson-Vanick bill was repealed as part of the so-called Magnitsky Act signed by President Barack Obama, which normalized trade but also punished several individuals connected to the death in prison of lawyer Sergei Magnitsky. That act prompted Putin to suspend U.S. adoptions of Russian children, an issue cited somewhat improbably by some of Trump’s advisers as the motive for their meetings with Russians during the election campaign.

One problem with the new Russia sanctions, Mankoff said, will be that — as with the Jackson-Vanic bill — they will outlive the Trump administration and constrain future presidents.

It is debatable how much impact ongoing sanctions have had on Russia. The U.S. and the European Union imposed measures following Putin’s aggression in Ukraine and annexation of Crimea in 2014. The Russian economy has suffered, but at least as much from falling oil prices.

New sanctions could hurt, however.

Europe, meanwhile, is also less than thrilled about the new round of sanctions, especially because European leaders were not consulted.

Several European countries worry that they will be caught up in the punitive measures as they attempt to do business with Russia involving a new proposed gas pipeline. It would supply much of Western Europe with Russian gas.
