Republican presidential candidate and Texas Sen. Ted Cruz is pushing back against President Barack Obama for making fun of the Republican field after the third Republican debate last week. Obama ridiculed the pack for complaining about the CNBC moderators during the debate, saying they couldn’t handle them. Cruz, in response, said the president is afraid of what he called “real journalists” on conservative radio.

“It’s not surprising that President Obama is taking cheap shots,” Cruz said on WTMJ, Milwaukee. The president is the “worst negotiator in the history of the world for the United States.”

“Every [Republican] goes on lefty journalist shows all day long,” he continued. “I go on MSNBC. I have liberal journalists take shots at me all day long. Have you ever seen Barack Obama sit down and be interviewed by Rush Limbaugh, or Sean Hannity, or Glenn Beck, or Mark Levin? Barack Obama is terrified of questions from real journalists who actually would press him. He likes to be surrounded by his fawning acolytes.”

Obama went after Republicans Monday for complaining about the third debate, in which the candidates were asked questions that provoked outrage on the stage. Some of the questions included whether or not one of the front-runners, Donald Trump, was running a “comic book campaign.”

“Have you noticed that every one of these candidates say, 'Obama's weak. Putin's kicking sand in his face. When I talk to Putin, he's going to straighten out,’ ” Obama said at a New York fundraiser. “Then it turns out they can’t handle a bunch of CNBC moderators at the debate. Let me tell you: If you can’t handle those guys, then I don’t think the Chinese and the Russians are going to be too worried about you.”

The fourth Republican debate will be held Tuesday in Milwaukee, and will be moderated by Fox Business. The candidates will be given more time to answer questions and respond to their opponents’ criticisms or statements.
