WASHINGTON — Forget President Trump’s problems within recalcitrant Republicans and oppositional Democrats. Now he’s facing a mob of menacing dinosaurs.

About 100 wobbly dinosaurs — OK, people dressed up in gigantic, plastic T. rex suits — roared and stampeded across the Capitol lawn on Wednesday morning.

“We’re coming to get you!” one bellowed.

Even by Washington standards for theatrical protests, it was quite a sight. The cause, in this case: the president’s proposed budget cuts to national service programs, such as AmeriCorps.

The dinosaur suits fit the motto of their PR blitz: “Stop national service extinction.”

“While dinosaurs are fun, national service extinction is a serious matter,” said Aly Ferguson, a spokeswoman for the Service Year Alliance, a nonprofit that encourages young Americans to spend a year doing public service, whether as teachers or health care providers.

She noted that hundreds of AmeriCorps members are in Texas right now, helping with the response to Hurricane Harvey. “If the president's budget becomes reality, these people would not be there helping during this natural disaster,” Ferguson said.

Trump’s budget for fiscal year 2018, which begins in October, calls for eliminating the Corporation for National and Community Service. National service and other volunteer programs should be funded by the private sector and other nonprofit groups, the White House argues.

Congress will have the final say on federal spending for 2018. Ferguson said they were counting on lawmakers to jettison Trump’s request.
