WASHINGTON — House Speaker Paul Ryan, who's in charge of the GOP-run House, is cracking down on Democrats' ability to win floor votes on hotly contested issues such as LGBT rights. With his move Wednesday, Ryan is turning his back on a promise that he would safeguard lawmakers' rights to take on a range of contentious issues when the House debated annual spending bills. When House worked on an energy bill in May, Democrats pushed through a symbolic measure supporting Obama administration policies that bar federal contractors from discriminating against lesbian, gay, bisexual and transgender people.
