Conservative media personality Glenn Beck will make appearances with Republican presidential candidate Ted CruzTed CruzMcConnell: Trump White House will have ‘constraints’ Cruz holds back support for Trump with eye on abortion Trump takes victory lap over rivals' remarks MORE on Saturday in Iowa, ABC News reported late Tuesday.
The news came shortly after Beck took to Facebook on Tuesday to attack Cruz's rival Donald TrumpDonald TrumpSanders mocks ‘tough guy’ Trump for changing mind on debate 35 arrested in clashes outside Trump rally Clinton email headache is about to get worse MORE and Sarah Palin, the 2008 GOP vice presidential nominee who endorsed Trump the same day.
"Small Government, lower taxes, fewer regulations and the constitution? Not any more," Beck wrote.
"Big government, bailouts, executive orders, not just abortion but partial birth abortion, nationalizing of banks, stimulus, pathway to citizenship."
He said all of these views were held by Trump during the Obama administration and asked what caused Trump to change his views so much.
Beck also accused Trump of giving money to prominent Democrats like House Minority Leader Nancy Pelosi (Calif.), Senate Minority Leader Harry Reid (Nev.) and Chicago Mayor Rahm Emanuel after "Sarah and the tea party won a hard fought election and were under attack.
"I couldn't disagree with her more but she has played the game now for years," he wrote. "Perhaps she knows more than those of us still on the outside."
Beck, a longtime opponent of Trump, said last week that it will be a "gigantic mistake if this country chooses Donald Trump" as its next president.
As president, Trump would be a "monster much, much worse" than President Obama, Beck added at the time.
Cruz and Trump are battling for first place in polls in Iowa, which are less than two weeks away.
In an interview with Fox News host Bill O'Reilly last week, Beck said that ”Cruz is my guy."
"Ted Cruz is a guy who says I'm for these principles, exactly like Ronald Reagan was, these are the principles and I'm going to be tethered and tied to these," Beck said.
He added that if Sen. Marco Rubio (R-Fla.) wins the GOP presidential nomination, he'd vote for him, but he has "real deep problems with Rubio."
