President Donald Trump just took to Twitter to go after the conservative House Freedom Caucus. 

"The Freedom Caucus will hurt the entire Republican agenda if they don't get on the team, & fast. We must fight them, & Dems, in 2018!" he wrote. 

The caucus, chaired by Rep. Mark Meadows (R-NC), opposed the American Health Care Act, which was championed by Trump and House Speaker Paul Ryan. 

The bill died on Friday without a vote due to opposition from the caucus members and some moderate Republicans. 

Sen. Lindsey Graham (R-SC) reacted on "America's Newsroom," telling Shannon Bream that he believes the president must put partisanship aside to address health care. 

He advised the president to allow ObamaCare to collapse, then reach out to both sides of the aisle to replace the law with something better. 

Graham said one-fifth of the nation's economy cannot be reformed using only Republican votes. 

"Challenge Democrats to help you fix their mess. ... Put America first and we'll all be OK. Don't let partisanship take over health care."

Later in the show, caucus member Jim Jordan (R-OH) reacted, saying that the health care bill was contrary to the Freedom Caucus' mission to "change Washington."

"We appreciate the president, we're trying to help the president. But look at the legislation. It doesn't do what we told the voters we were gonna do," said Jordan, noting the bill was polling at just 17 percent.
