Presumptive Republican presidential nominee Donald Trump has become a born-again Christian, according to one of the country's most prominent evangelical leaders.

Focus on the Family Founder James Dobson said Trump has accepted Christ, a step towards salvation in most Evangelical faiths.

"Trump did accept a relationship with Christ," Dobson said in a radio interview last week. "I know the person who led him to Christ, and that's fairly recent."

Dobson referred to Trump as a "baby Christian."

"I don't know when it was, but it has not been long," Dobson said. "And I believe he really made a commitment. He's a baby Christian... (Christians) need to be praying for him."

Trump's campaign has not confirmed Dobson's statements, which came less than a week after the business mogul-turned-politician met with a group of prominent evangelical leaders.

Dobson and other evangelicals have offered support for Trump, even as they have expressed concern for his abrupt style and sometimes crude comments. Dobson said as a new member of the faith, Trump - who was raised Presbyterian - is still in the early stages of his faith journey.

"He doesn't know our language. You know, we had 40 Christians together with him. He used the word hell four or five times. He doesn't know our language, he really doesn't. And he refers a lot to religion and not much to faith and belief," Dobson said. "You got to cut him some slack, he didn't grow up like we did. I think there's hope for him."

"And I think there's hope for us," he added.
