Trump told reporters he did not "feel like I have to go to Kansas," a Midwestern state where Senator Roger Marshall, a fellow Republican, is in an unexpectedly competitive race with Democratic challenger Adam Hamilton. "He is doing very well," Trump said of Marshall. "We are going to have a strong Tuesday night."
