Senate Democrats are playing the "hookers" card. Sen. David Vitter (R-La.) has been tying up the Senate this week as he pushes an amendment that would bar the federal government from making payments toward health insurance that members of Congress buy in the Obamacare exchanges. Vitter has been trying to attach the proposal to an unrelated bill on energy efficiency. Politico reports that Democrats have a response: If Vitter keeps pushing his amendment, they might advance one that strips the government contribution toward health benefits for any senator or congressman if the Ethics Committee has "probable cause to determine" that he (or, I suppose, she) hired a prostitute.
