Senator John Curtis, a Republican from Utah, is facing backlash from President Trump's supporters for being insufficiently loyal. Despite being viewed with suspicion by Trump's backers, Curtis has positioned himself as a member of the president's 'board of directors,' willing to disagree with him when necessary. As the Senate prepares to consider three of Trump's nominees, Curtis may face further scrutiny as a potential swing vote. He has previously expressed a willingness to break with Trump on issues important to Utahns, but it remains to be seen whether he will challenge the president on anything.
