Louisiana Gov. Bobby Jindal recently issued a blistering criticism of Donald Trump, calling his GOP presidential rival an "unstable narcissist" and questioning the faith of the controversial businessman.
"It's been a lot of fun, but here's the problem: Donald Trump is not a serious candidate," Jindal said in a speech given at the National Press Club in Washington, D.C., on Thursday.
"He's a narcissist. He's an egomaniac. The only thing he believes in is himself. The reality is that, I want to say what everybody is thinking about Donald Trump, but is afraid to say," he continued.
"Like all narcissists, Donald Trump is insecure and weak, and afraid of being exposed. And that's why he is constantly telling us how big and how rich and how great he is, and how insignificant everyone else is," Jindal said. "We've all met people like Trump, and we know that only a very weak and small person needs to constantly tell us how strong and powerful he is. Donald Trump believes that he is the answer to every question."
In a video released by his campaign, Jindal also compared Trump to controversial actor Charlie Sheen and called attention to a recent interview, where the Republican frontrunner couldn't name his favorite Scripture verse despite claiming the Bible was his "favorite book."
"You may have recently seen that after Trump said the Bible is his favorite book, he couldn't name a single Bible verse or passage that meant something to him," he said. "And we all know why, because it's all just a show, and he hasn't ever read the Bible. But you know why he hasn't read the Bible? Because he's not in it."
In continuing his comments on Thursday, Jindal warned that Trump will undoubtedly harm the GOP's chance of winning the general election of he wins the Republican nomination.
"We can 'make America great again,' but we will not do that by putting an unserious and unstable narcissist in the White House."
The Louisiana Republican added that Trump "is shallow. Has no understanding of policy. He's full of bluster but has no substance. He lacks the intellectual curiosity to even learn."
Jindal is not the only GOP presidential contender to criticize Trump, who currently leads the GOP field with 32 percent, according to a recent CNN/ORC poll. Speaking to reporters before a large rally in Anaheim, Dr. Ben Carson, who took 19 percent support in the same poll, also called Trump's faith into question when asked by a reporter how he differed from the billionaire businessman.
"Probably the biggest thing -- I've realized where my success has come from and I don't in anyway deny my faith in God," Carson said.
"By humility and the fear of the Lord are riches and honor and life and that's a very big part of who I am. I don't get that impression with him," Carson said of Trump. "Maybe I'm wrong, but I don't get that."
In a Thursday morning interview on CNN, Trump responded by challenging both Carson's faith and his ability as a neurosurgeon.
"He makes Bush look like the Energizer Bunny," Trump said. "...If you look at his past, which I've done, he wasn't a big man of faith. All of a sudden he's become this man of faith. And he was heavy into the world of abortion."
