President Donald Trump campaigned on “draining the swamp” in Washington, but one swamp monster seems to have found its way to a Senate hearing on Thursday.

A woman seated behind acting Secretary of the Interior David Bernhardt donned a mask during the opening remarks at Bernhardt’s confirmation hearing before the Senate Energy and Natural Resources Committee.

Bernhardt’s past work as an oil and gas lobbyist has received scrutiny and claims of conflicts from a number of environmental groups. During his time as deputy secretary, The Washington Post reported that Bernhardt carried a small card with him to keep track of his long list of conflicts of interest.

Rep. Don Beyer (D-Va.) shared a screenshot of the Senate hearing, joking that Bernhardt was the real “swamp monster” in the photo.

“But seriously, the US Senate should reject oil lobbyist David Bernhardt’s confirmation,” he added.

SPOTTED in the US Senate: a swamp monster!

“Can you spot the swamp monster?” the Natural Resources Defense Council tweeted.

Can you spot the swamp monster?

Trump said he’d “drain the swamp” but he’s trying to put David Bernhardt—a former oil lobbyist!—in charge of @Interior.

Public Citizen, a progressive consumer advocacy group, claimed Bernhardt has “more conflicts of interest than [former EPA Administrator Scott] Pruitt, [former Interior Secretary Ryan] Zinke, [former Health and Human Services Secretary Tom] Price and [former Veterans Affairs Secretary David] Shulkin combined.”

It looks like a swamp monster is trolling Interior nominee and former oil lobbyist David Bernhardt at his confirmation hearing.

The “swamp monster” was reportedly escorted out of the hearing shortly before noon.
