The Kansas Republican said the idea of using increased IRS enforcement to generate some of the nearly $600 billion in new spending “has some red flags among Republicans,” who have openly worried about being targeted by the Biden administration. Moran’s also concerned his vote for a bipartisan bill could help kick off a massive subsequent round of spending by Senate Democrats on party lines. “Part of the motivation is trying to make certain that we don’t spend $6 trillion," Moran said on Monday evening. If "this is lending itself toward that outcome then I would no longer be a yes at that point in time." Moran isn’t alone. Another of the framework’s supporters, Sen. Mike Rounds (R-S.D.), said at the moment he is not 100 percent committed to voting for the bipartisan plan. “We don’t know what’s in it yet,” Rounds said. “I’m favorably impressed with what’s been done, but we’re going to wait and look at the final thing. So there’s still a lot of negotiations going on.”
