Who says the charities are helping them with Obama's money? I doubt the government is paying the charities anything for their help.
And even if the government did, taxes aren't robbery. Taxes are ligitimate and Christians are to pay them.
In any event, the story about Jesus was that it was prophesized that the messiah would have a zeal for His Father's house. Jesus ran then out of the temple because they were preventing prayer. Jesus wasn't against merchants in general. This is a completely different situation and in no way like the story of Jesus running the merchants out of the temple.
The charities aren't merchants. They aren't preventing people from worshipping. They are helping people. They maybe helping people that are illegally here. But it's not the Christian charity's job to enforce immigration. It's their job to love others and to win people for Christ.
Let Ceasar close the border. And let the Christian charities love anyone they can.

Well ok, Obama(Herod).
