A growing political war of words over whether to take in Syrian refugees in the wake of last week's terror attack in Paris may be morphing into the next government shutdown showdown.

Alabama Sen. Jeff Sessions sent a letter to colleagues Monday urging them to support adding language to the next government spending bill that would effectively block President Barack Obama's plan to accept 10,000 Syrian refugees in the next fiscal year. Obama on Monday said he intends to go forward with his plan, despite numerous calls from Republican presidential candidates and governors that he scrap it.

Sessions is proposing that Congress explicitly prohibit any funding for Syrian refugee resettlement unless Congress approves it and finds money to offset the cost.
