Bremer serves as a Senior Fellow of ACUS, a co-editor of the administrative law section of Jotwell, and a regular contributor to the Yale Journal on Regulation’s Notice & Comment blog.

Judge, United States Court of Appeals, Second Circuit
Judge Menashi was appointed to the U.S. Court of Appeals for the Second Circuit on November 14, 2019. Previously, he served as special assistant and associate counsel to the President in the White House and as acting general counsel at the U.S. Department of Education. He was assistant professor of law at Scalia Law School, George Mason University, where he taught administrative law and civil procedure, and a research fellow at New York University School of Law and Georgetown University Law Center. He was also a partner at Kirkland & Ellis LLP in New York, where he practiced appellate and commercial litigation, and served as a law clerk to Justice Samuel Alito on the Supreme Court of the United States and to Judge Douglas Ginsburg on the U.S. Court of Appeals for the District of Columbia Circuit. He graduated from Stanford Law School, where he was elected to Order of the Coif and served as senior articles editor of the Stanford Law Review, and from Dartmouth College, where he was elected to Phi Beta Kappa.
Andrew Tutt focuses on Supreme Court, appellate, and complex litigation. He has won cases in federal courts across a broad cross-section of subjects, with particular experience in administrative law, intellectual property law, and civil rights law. He has argued and won three cases in the United States Supreme Court, led appeals in the First, Second, Third, Fourth, Fifth, Sixth, Seventh, Ninth, Tenth, and D.C. Circuits and led the strategy, briefing, and argument in complex cases in federal district courts nationwide.
Recently, Andrew argued and won a significant victory in the United States Supreme Court establishing an important structural constitutional principle and safeguarding the reemployment rights of thousands of veterans and servicemembers. The Court took the rare step of granting certiorari to a state intermediate court of appeals, without a circuit conflict, over the Solicitor Generals recommendation that the Court deny the case.
In another recent matter before the United States Supreme Court, Andrew identified a meritorious pro se petition for certiorari. Representing the petitioner pro bono, Andrew and a team of Arnold & Porter attorneys persuaded the United States Supreme Court to grant the petition, securing reversal and his clients release from federal custody.
In a recent case, Andrew persuaded the Fourth Circuit to recognize that livestreaming police officers in the discharge of their duties is First Amendment protected activity.
In another recent case, Andrew convinced the Tenth Circuit to join six other federal courts of appeals in recognizing that individuals have a clearly established First Amendment right to record police officers in the discharge of their duties in public subject only to reasonable time, place, and manner restrictions.
In another case, Andrew persuaded the Fourth Circuit that a federal district court fundamentally misapprehended the evidence and arguments in a high-stakes bench trial, winning, on clear error review, a reversal and remand with instructions to enter judgment in favor of his client.
In another case in the Fourth Circuit, Andrew won a preliminary injunction and summary judgment for the City of Baltimore against changes to grant criteria used to award nearly US$300 million annually. On appeal, the Fourth Circuit granted initial hearing en banc, split with the en banc Ninth Circuit, and affirmed the district court's grant of summary judgment on four independent grounds.
In the Ninth Circuit, Andrew successfully represented three federal grantees in a high-profile challenge to the criteria used to award US$100 million in annual federal grants. Andrew persuaded the court of appeals to reverse the district court's dismissal for lack of jurisdiction and exercise its discretion to reach the merits and strike down the unlawful award criteria in light of the case's "national impact."

Judge, United States Court of Appeals, Second Circuit
Judge Menashi was appointed to the U.S. Court of Appeals for the Second Circuit on November 14, 2019. Previously, he served as special assistant and associate counsel to the President in the White House and as acting general counsel at the U.S. Department of Education. He was assistant professor of law at Scalia Law School, George Mason University, where he taught administrative law and civil procedure, and a research fellow at New York University School of Law and Georgetown University Law Center. He was also a partner at Kirkland & Ellis LLP in New York, where he practiced appellate and commercial litigation, and served as a law clerk to Justice Samuel Alito on the Supreme Court of the United States and to Judge Douglas Ginsburg on the U.S. Court of Appeals for the District of Columbia Circuit. He graduated from Stanford Law School, where he was elected to Order of the Coif and served as senior articles editor of the Stanford Law Review, and from Dartmouth College, where he was elected to Phi Beta Kappa.
Andrew Tutt focuses on Supreme Court, appellate, and complex litigation. He has won cases in federal courts across a broad cross-section of subjects, with particular experience in administrative law, intellectual property law, and civil rights law. He has argued and won three cases in the United States Supreme Court, led appeals in the First, Second, Third, Fourth, Fifth, Sixth, Seventh, Ninth, Tenth, and D.C. Circuits and led the strategy, briefing, and argument in complex cases in federal district courts nationwide.
Recently, Andrew argued and won a significant victory in the United States Supreme Court establishing an important structural constitutional principle and safeguarding the reemployment rights of thousands of veterans and servicemembers. The Court took the rare step of granting certiorari to a state intermediate court of appeals, without a circuit conflict, over the Solicitor Generals recommendation that the Court deny the case.
In another recent matter before the United States Supreme Court, Andrew identified a meritorious pro se petition for certiorari. Representing the petitioner pro bono, Andrew and a team of Arnold & Porter attorneys persuaded the United States Supreme Court to grant the petition, securing reversal and his clients release from federal custody.
In a recent case, Andrew persuaded the Fourth Circuit to recognize that livestreaming police officers in the discharge of their duties is First Amendment protected activity.
In another recent case, Andrew convinced the Tenth Circuit to join six other federal courts of appeals in recognizing that individuals have a clearly established First Amendment right to record police officers in the discharge of their duties in public subject only to reasonable time, place, and manner restrictions.
In another case, Andrew persuaded the Fourth Circuit that a federal district court fundamentally misapprehended the evidence and arguments in a high-stakes bench trial, winning, on clear error review, a reversal and remand with instructions to enter judgment in favor of his client.
In another case in the Fourth Circuit, Andrew won a preliminary injunction and summary judgment for the City of Baltimore against changes to grant criteria used to award nearly US$300 million annually. On appeal, the Fourth Circuit granted initial hearing en banc, split with the en banc Ninth Circuit, and affirmed the district court's grant of summary judgment on four independent grounds.
In the Ninth Circuit, Andrew successfully represented three federal grantees in a high-profile challenge to the criteria used to award US$100 million in annual federal grants. Andrew persuaded the court of appeals to reverse the district court's dismissal for lack of jurisdiction and exercise its discretion to reach the merits and strike down the unlawful award criteria in light of the case's "national impact."
