The Foreign Emoluments Clause of the Constitution will be rendered meaningless if Democrats in Congress aren't allowed to sue President Trump for violating it, a lawyer for nearly 200 Democratic senators and representatives told a federal judge today.

"There's simply nothing Congress can do to stop the president's actions, no matter who's in control of the body," said Brianne Gorod, chief counsel of the Constitution Accountability Center, representing the Democratic lawmakers.

Environmental Protection Agency Administrator Scott Pruitt, already battling roughly a dozen ethics investigations, allegedly asked a top aide to obtain a used mattress from President Trump's Washington, D.C., hotel.

Millan Hupp, Pruitt's director of scheduling and advance, told House investigators last month that she couldn't track down the mattress, and didn't know if Pruitt ultimately got one.

A spokeswoman for the Trump International Hotel had no comment on any aspect of the story.

As tech companies and government agencies prepare to defend against possible Russian interference in the midterm elections, the Federal Election Commission has a different response: too soon.

The four commissioners on Thursday deadlocked, again, on proposals to consider new rules, for example, for foreign-influenced U.S. corporations and for politically active entities that don't disclose their donors.

Emory Rounds III, President Trump's nominee to lead the Office of Government Ethics, got a warm if brief welcome Wednesday from a Senate committee.

Sen. Tom Carper, D-Del., summed up senators' concerns about OGE, which has gone toe-to-toe with the Trump White House several times. Carper asked Rounds, "Are you confident you can maintain independence from this White House, and when necessary hold it accountable?"

Rounds replied, "I certainly intend to do so, yes sir."
