A Christian campaign group wants Franklin Graham to stand down from his role at Samaritan's Purse or for the board to resign in protest.
Samaritan's Purse provides aid to people in poverty and emergency response across the world, such as pop-up hospitals during the pandemic, or organising the shoe box Christmas presents for children in poorer nations.
Billy Graham's son Franklin Graham is the CEO and President of Samaritan's Purse but also a passionate Trump supporter, attending his rallies and praying for the President.
The Christian group 'Faithful America', who exist to challenge the use of Christian language used by the American right and stand up for social justice, say they are "sick of sitting by quietly while Jesus' message of good news is hijacked by the religious right to serve a hateful political agenda."
At the Republican National Convention last week, Graham thanked God for the "great bounty" He had bestowed on the nation and the "many blessings" Graham said the country had received "these past four years." He prayed for Donald Trump, Mike Pence and their families as well as for unity and dependence on God's word and wisdom.
The petition by Faithful America says: "We would hardly consider family separation, the deadly federal COVID-19 response, rampant corruption and authoritarianism, or ongoing systemic racism to be 'blessings.'
"Graham justifies his partisanship and hatred by hiding behind the credibility of Samaritan's Purse...If the directors of Samaritan's Purse care about their credibility - and if they truly believe in their 'purpose of sharing God's love' - then Graham's hateful support for Trump should show them that it's time to find a new chairman and CEO."
The petition has 12, 475 signatories at the time of writing and will be sent to all the board members.
They go on to say the charity needs a leader who is not "complicit in separating families, rejecting refugees, repealing health care, slowing COVID-19 testing, spreading homophobia and Islamophobia, or supporting anti-Semitic neo-Nazis."
