Trump is not the only Republican candidate whose philanthropic giving is being measured, and found wanting; Ted Cruz continues to receive criticism for his 1% charitable giving.
"As the Iowa primary approaches, Ted Cruz is facing criticism from rivals over his lack of tithing as indicated by tax returns for 2007-2010 disclosed when he ran for Senate. The Cruz family reported donations which amounted to about 1% of their income.
"Some Christians who have spoken quite favorably of Cruz believe God requires Christians to give 10% to the church. For instance Gateway Church pastor Robert Morris has preached that Christians are cursed if they don’t tithe (see the video at the end of the post) and Gateway Church doesn’t allow non-tithers to volunteer. In late December, Morris attended a meeting in Texas along with other evangelicals for a meet and greet with Cruz, arranged by David Barton, the head of one of Cruz’s Super PACs."--Warren Throckmorton, Patheos
