Texas ended its contentious legislative session Monday as protesters packed into the state Capitol over a new ban on sanctuary cities, and lawmakers erupted into a heated argument with alleged death threats on the House floor. The chaotic last day at the legislature marked a symbolic end to a polarizing session that had considered issues such as sanctuary cities, bathrooms used by transgender teens and religious objections. One of the most heated debates during the session was around Senate Bill 4, which was signed into law by Gov. Greg Abbott. The new law, which goes into effect in September, bans sanctuary cities and punishes local governments that don't comply with immigration laws and detention requests. It was a whirlwind last day of the 85th Texas Legislature, but there may be more this summer.
