As Texas braces for its notoriously scorching summer temperatures, the state House agreed to install air conditioning in dozens of uncooled prisons within seven years — but only if lawmakers specifically set aside money for it. On Thursday night, the Texas House initially passed a bill that would require all Texas lockups to be cooled over a seven-year span, capping costs at $300 million. But the state prison agency would only have to abide by the measure if lawmakers also agree to specifically provide state or federal funds toward cooling costs. The bill still needs to clear a final vote in the House Friday before moving to the Senate.
