Speaking on Fox News, the Dallas, Texas pastor responded to critics that have called evangelical supporters of the president "hypocrites" since Stormy Daniels' allegations came to light.
"Well, it's absolutely ludicrous," Jeffress said to host Martha MacCallum.
"Evangelicals know they're not compromising their beliefs in order to support this great president.
"And let's be clear - evangelicals still believe in the commandment 'thou shalt not have sex with a porn-star'... however, whether this president violated this commandment or not is totally irrelevant to our support of his for two quick reasons.
"First of all evangelicals knew they weren't voting for an altar boy when they voted for Donald Trump. We supported him because of his policies and his strong leadership.
"Secondly... evangelicals understand the concept of sin and forgiveness. Look, we are all sinners, we all need forgiveness - that forgiveness is available through Christ for anyone that asks. Whether the president needs that forgiveness for this particular allegation, whether he's asked for it is between him, his family and his God."

However, Jeffress was challenged by political analyst Juan Williams who used scripture to make his point.
"By the way, what did Christ do at the temple - he threw out the money changers," Williams argued.
"Pastor, you cannot sell your integrity, your Christian values and say, 'oh because President Trump is anti-abortion I'll support him no matter what'. What happened to the principles? What happened to your love of people of character?"
When asked if the support is likely to continue, Jeffress answered: "What would it take for evangelicals to walk away from President Trump? I'm his friend, I'll never walk away but I think if his policy changes or if he were found to be in an adulterous relationship now, that would cause for many people a problem."
