Republican U.S. Senator Lindsey Graham came under fire Friday for being the only lawmaker to sign on to a GOP self-enrichment scheme.

Jake Sherman appeared on MS NOW ahead of the weekend, where he was asked about a ploy that would allow senators who are investigated by the government to sue for potentially millions of dollars. Specifically, the host asked him, "Why in the world they thought it was a good idea to tuck this into the shutdown bill and whether they expected this blowback."

"I could not give you any reason why anybody with a brain thought this was a good idea politically," Sherman replied. "I mean, substantively, what they're trying to do is they're trying to discourage the administration from any administration, from spying on on senators. I mean, that's what they say they're trying to do, and they're trying to make there be a recourse if they do. So if DOJ or some other investigatory agency surveils your data. The couple of interesting things here. Right. Like this is only for senators, right. So ... if you're a member of the House and your data was surveilled and collected, then you're not able to sue. So that's number one. Number two, as you said, Katie, this is taxpayer money."

So far, according to Sherman, Graham is on an "island" as the only senator to say he would take advantage of the policy.
