A federal appeals court on Friday threw out U.S. Sen. Richard Blumenthal’s legal challenge of President Donald Trump, a lawsuit that alleged the president is improperly profiting from his position.

The Connecticut senator is the lead plaintiff in Blumenthal v. Trump, a case brought by more than 200 Democratic lawmakers who sued Trump, arguing that Congress has the right to approve — or withhold — consent before the president accepts payments or benefits from foreign governments.

But a three-judge panel on the U.S. Circuit Court for the District of Columbia said Democrats who brought the lawsuit, based on the emoluments clause of the U.S. Constitution, had no standing to sue because they did not represent a majority in the U.S. House of Representatives or the U.S. Senate.

“Here, regardless of rigor, our conclusion is straightforward because the members—29 Senators and 186 members of the House of Representatives—do not constitute a majority of either body and are, therefore, powerless to approve or deny the President’s acceptance of foreign emoluments,” the opinion reads.

Blumenthal said “I am deeply disappointed and alarmed by this decision.”

“This dismaying decision adds to the already widespread fear that the checks on unbridled presidential power, corruption, and self-enrichment have been seriously undermined,” Blumenthal said.

The senator also left open the possibility of an appeal to the Supreme Court.

“As we evaluate next steps, we remain fully committed to doing everything in our power to hold President Trump accountable for his unacceptable, unconstitutional misconduct,” Blumenthal said.

The judges only ruled on the issue of whether the members had standing. They did not rule on a district court’s earlier finding that the Democrats had a cause of action and a claim against the president.

The non-profit Constitutional Accountability Center represented the lawmakers in Blumenthal v Trump.

“While we are disappointed in the panel’s decision and are in active discussions with our clients as they consider their next steps, it is important to recognize that today’s ruling is not a decision on the merits,” said Constitutional Accountability Center President Elizabeth Wydra. “The Court of Appeals did not in any way approve of President Trump’s repeated and flagrant violations of the Constitution’s Foreign Emoluments Clause.”

Trump reacted through Twitter, a favorite form of expression.

“Another win just in,” the president tweeted. “Nervous Nancy Pelosi and the Democrats in Congress sued me, thrown out. This one unanimous, in the D.C. Circuit. Witch Hunt!”
