The Leader of the Free World doesn’t need Donald Trump to have his back, the billionaire developer said in a Twitter blast Saturday.

“Am I morally obligated to defend the president every time somebody says something bad or controversial about him? I don’t think so!,” Trump wrote, referring to his refusal to correct a man who called President Obama a Muslim at a campaign event Thursday.

“This is the first time in my life that I have caused controversy by NOT saying something,” he added. “If someone made a nasty or controversial statement about me to the president, do you really think he would come to my rescue? No chance!”

A New Hampshire man said Muslims were a “problem in this country,” that the President is not American, and asked Trump “when can we get rid of them?” during a Rochester, New Hampshire town hall.

He defended himself on Twitter Saturday saying if he would have corrected the man, “the media would have accused me of interfering with that man’s right of free speech. A no win situation!”

“Christians need support in our country and around the world, their religious liberty is at stake!” Trump continued. “Obama has been horrible, I will be great.”

Trump has challenged Obama’s faith and citizenry for years.

He suggested Obama was born in Kenya, that he does not have a birth certificate, and that his religion is Islam in a Fox News appearance in 2011.

And he repeatedly called for Obama to release his long-form birth certificate until the president posted a copy on the wall of the White House briefing room in April 2011 and denounced Trump’s “silliness.”

But Obama got the last laugh in their skirmish when he savaged Trump at the 2011 White House Correspondents Dinner on April 30.

“No one is happier, no one is prouder to put this birth certificate matter to rest than the Donald,” said Obama. “That’s because he can finally get back to focusing on the issues that matter, like, did we fake the moon landing? What really happened in Roswell? And where are Biggie and Tupac?”
