President Donald Trump signed a Russia sanctions bill Congress forced on him, adding a statement saying the administration will carry out the law but with reservations about its impact and the constitutionality of some provisions.

In a statement Wednesday accompanying the notice that he signed into law the legislation, which also targets Iran and North Korea, Trump laid out a list of concerns. He said it encroaches on presidential authority, may hurt U.S. ability to work with allies and could have unintended consequences for American companies. 

“While I favor tough measures to punish and deter aggressive and destabilizing behavior by Iran, North Korea, and Russia, this legislation is significantly flawed,” the statement released by the White House said.

Trump’s statement doesn’t signal any intent to bypass or circumvent aspects of the law. Instead, the president indicates he intends for his administration to carry it out in a way consistent with his constitutional authority, language that leaves open some room for interpretation of how the law is executed.

Trump’s concerns cover four areas: encroachment on executive authority, unintentional harm to U.S. companies and business, as well as U.S. international partners, and limits on the flexibility of the administration to act in concert with allies in dealing with Russia.

The European Union has warned of possible retaliation if European companies are hobbled by sanctions aimed at squeezing Russia’s energy exports.

Veto-Proof

The legislation, passed by overwhelming, veto-proof margins in the U.S. House and Senate, strengthens sanctions on Russia and gives Congress the power to block the president from lifting them.

The Russia sanctions and the restrictions placed on Trump marked a rare rebuke for the president from congressional Republicans. Lawmakers decided to limit the president’s ability to ease penalties on Russia at a time when House and Senate committees and the Federal Bureau of Investigation are examining whether some members of his political campaign may have colluded with Russia’s interference in the 2016 presidential campaign.
