President Joe Biden has approved a major disaster declaration for Texas as the state grapples with widespread power outages and water shortages amid freezing winter conditions, the Federal Emergency Management Agency announced on Saturday.

Millions of Texans have struggled with power outages and more than half the state is experiencing disrupted water service with boil-water notices in effect.

More than 14 million people in Texas were told to boil their water as of Friday because parts of the state's water supply might be contaminated.

The federal government has already approved emergency declarations for Texas, Oklahoma and Louisiana and has sent supplies like generators, blankets, water and meals to Texas last week.

More than 78,000 people in Texas still didn't have power as of 10:30 a.m.
