Lawmakers are raising separation-of-powers concerns as the White House seeks to install a Justice Department official at the legislative branch institution.

In a rare bipartisan effort to defend its institutional authority, Congress is quietly resisting President Donald Trump’s attempt to assert control over the Library of Congress — a move that experts say threatens the separation of powers and the integrity of the legislative branch’s premier research body.

On Capitol Hill, Democrats said Tuesday they did not believe Blanche was the acting librarian — and Republicans, who have repeatedly deferred to Trump even as he has wrested control of federal spending from authorities, indicated that they wanted to maintain their power around the library, which is part of the legislative branch even though the president nominates its leader.

“It’s the Library of Congress, not the library of the executive branch,” House Minority Leader Hakeem Jeffries (D-New York) told reporters. “This is an example of executive overreach.”
