One of America's most well known evangelicals has given his strongest hint yet that Christians should support Donald Trump.

Rev Franklin Graham, son of legendary evangelist Billy Graham, has commentated throughout the election season. Yet he left it late – the eve of polling day itself – to give a strong boost to the GOP candidate.

While he stopped short of offering an official endorsement, Graham said, "You may have to hold your nose and vote... I have people that say, 'Well I don't like Donald Trump, I don't like what he says.' Well I don't like what he said either, I promise I don't like it. But those are things that he said 11 years ago, not something that he said today. I think Donald Trump has changed. I think God is working on his heart and in his life. But people have to make up their own mind."

Graham also claimed that Trump has changed and isn't the same man he was 11 years ago when a microphone picked him up discussing grabbing women. He also told the Christian Post, "There's two different pictures and two different visions for America. The Democratic Party has a vision, Hillary Clinton has a vision, Donald Trump has a totally different vision for this nation with the Republican Party. This isn't difficult to figure out if you are a Christian."

However, while some of Graham's fellow evangelicals will follow his advice, many others have remained steadfast in their opposition to Trump.
