“That’s not the way the government works,” Kennedy said on Fox News. “You can’t just take $1 billion from this program, $1 billion from over here, and then put it toward your pet project.”

She claimed that if Obama had taken money from the U.S. defense budget and put it toward a solar company, Republicans would "all be up in arms."

"It's really not OK," Kennedy said. "It's not how the government should function."

"If the president wasn’t able to get this funding when he had both chambers, it just goes to show what a politically toxic issue this is," she continued.

Republicans leaders and pundits railed on Trump Wednesday after the White House dropped its demand that $5 billion for Trump's border wall be included in a government funding bill.

The White House this week began discussing other funding options.

Conservative commentator Ann Coulter said Wednesday that she won’t vote to reelect Trump if no progress has been made on the U.S.-Mexico border wall by 2020.

"Well, I’m not going to sugarcoat it," conservative columnist Michelle Malkin told Fox News on Wednesday. I’m not going to spin it. I wish I could but I can’t. This is a cave. This was a blink."
