If President Donald Trump declares a national emergency in order to fund his proposed wall at the Mexican border, it will set a "bad precedent," Senate Finance Committee Chairman Chuck Grassley said Friday.
‘I think it’s a bad precedent and it contravenes the power of the purse that comes from the elected representatives of the people," the Iowa Republican told CNBC's "Squawk Box."
Instead, negotiations are still necessary to resolve the government shutdown, with government workers on Friday missing their first paychecks during the impasse between Trump and House Democrats over the wall.
Negotiations between Trump, House Speaker Nancy Pelosi, and Chuck Schumer ended on Wednesday with the president calling the talks a "total waste of time."
Grassley Friday said if Trump declares a national emergency, it will end up being challenged in the courts "almost immediately."
He also said he doesn't understand why there can't be a compromise, as many in both the House and Senate have already supported 650 miles of fence, and the difference between what Congress has agreed to spend and what Trump wants can be split.
Further, there are many Republicans who want something to be done for those supported through the Deferred Action for Childhood Arrivals (DACA) program, said Grassley.
"It seems there's plenty of opportunity here to compromise but Pelosi wants to be just very anti-Trump and respond to her caucus in a way that shuts down government," said Grassley.
