“Chief Justice Roberts rebuked Trump for a comment he made [about a] judge’s decision on asylum,” Grassley said in a tweet on Wednesday. “I don’t recall the Chief attacking Obama when that Prez rebuked Alito during a State of the Union.”

Grassley, the Judiciary Committee Chairman, appeared to be referencing a State of the Union address Obama gave in 2010, where Obama criticized the Supreme Court’s 5-4 landmark decision in Citizens United v. Federal Election Commission. The decision eased restrictions that blocked corporations and unions from funding political campaigns without limits.

But Obama did not single out Justice Samuel Alito during that State of the Union address. Obama referred to the Supreme Court broadly, without mentioning any names.
