On Wednesday's show: The Texas House is debating private school vouchers while the U.S. House votes on a budget. We discuss those and other developments in politics in our weekly roundup.

Also this hour: CERAWeek, one of the most important annual conferences for the energy industry, is happening now in Houston, bringing in executives, foreign ministers, top officials, and more than 10,000 participants to discuss energy strategies in a time of climate change and political upheaval. We learn how Houston is more than just the host of this major event.

And what constitutes the perfect Houston sandwich? Where do you go for the Bayou City’s best bread, meats, cheeses, veggies, and sauces? We begin a month-long quest to create the ultimate Houston sandwich.
