More than an hour of delaying tactics from House Democrats has blocked a vote on a hotly debated bill that would have mandated drug testing for some welfare applicants.
Lawmakers earlier Tuesday night approved a measure requiring some people seeking unemployment insurance to undergo drug screening.
But a proposal requiring such testing for people enrolled in Temporary Assistance for Needy Families wasn't voted on before a key midnight deadline.
It had already passed the Senate and was backed by Gov. Rick Perry.
The measure would have required applicants to answer questions to see if they are at risk of abusing drugs.
If they failed the screening, they would have been required to take a drug test. If the person tests positive, state officials could have suspended the person's benefits.
