I would call them at their bluff

This one was heard on MSNBC’s Morning Joe, uttered by Joe himself. He was talking about the 10 GOP Senators who were in the Oval Office proposing a counteroffer to Biden’s 1.9 trillion COVID relief bill and was suggesting that President Biden “call them at their bluff”. This is a conflation of “call (one’s) bluff” (challenge someone to act on their threat or prove that their claim is true, when one believes they are making a false claim) and “take (one) at (one’s) word” (accept what one says without further verifying). A big thank you to Mike Kovacs for hearing this one and promptly sending it in!
