The Week in the Rearview Mirror

Their main tactic? Trying to poke holes in the scientific consensus behind the regulation.

In Texas' latest salvo against Obamacare, Attorney General Ken Paxton has filed suit over a fee states must help cover to pay for the sweeping federal health reform law. Texas joins Louisiana and Kansas in suing the Obama administration over the Health Insurance Providers Fee, which Paxton says cost Texas $86 million in 2013 and about $120 million per year since.

The office of Attorney General Ken Paxton says he is recusing himself from some of his professional responsibilities as he fights an indictment on securities fraud charges. Calling it a common procedure, a Paxton spokeswoman said Wednesday the office is working to remove him from "active participation in matters in which a conflict may exist." Those areas specifically relate to the State Securities Board and the Texas Ethics Commission, according to the spokeswoman, Cynthia Meyer.

University of Texas System Regent Wallace Hall has renewed an old request for information about the workloads of faculty, prompting all-too-familiar exchanges about whether his requests are too burdensome.

The political anarchy among U.S. House Republicans could be coming to an end, as U.S. Rep. Paul Ryan, R-Wis., announced Tuesday that he would run for speaker of the House if all warring GOP factions agree to back him.

Speculation about U.S. housing secretary Julián Castro's Democratic vice presidential prospects is reaching a boil with his endorsement last week of former Secretary of State Hillary Clinton. Despite the growing frenzy, Democrats acknowledge that it's remarkably early to be talking about Clinton’s choices for vice president. But the early timing has done little to curb months-long rumors that 41-year-old Castro has the inside track for running mate.
