Donald Trump tried to get the attention back on himself after Scott Walker's decision to end his presidential campaign dominated headlines by restarting his war with Fox News after appearing on the cable news channel.
Trump said Fox News host Bill O'Reilly treated him "unfairly" because the host didn't use polls that were more favorable to the Republican presidential candidate.
"He wants people to like him. When people criticize him, he takes it personally. And then, you know, this machine, this tweeting thing, that's like the worst thing you could give Donald Trump is this tweeting thing," O'Reilly told Matt Lauer on TODAY. "So I just think this is just an extension of his reality show."
