WASHINGTON (AP) — The Supreme Court will hear arguments Wednesday in a fight over plans to store nuclear waste at sites in rural Texas and New Mexico.

The U.S. Supreme Court is set on Wednesday to consider whether the Nuclear Regulatory Commission has the authority to license nuclear waste storage facilities amid objections brought by the states of Texas and New Mexico as well as the oil industry.

The Supreme Court's conservative majority ruled for San Francisco in limiting the power of environmental regulators to prevent ocean discharges of polluted stormwater.

The conservative Supreme Court aligned with liberal San Francisco on Tuesday, ruling that federal environmental regulators overstepped their authority by attempting to impose vague limits on how much raw sewage the California city may pump into the Pacific Ocean.

The Supreme Court seemed likely Tuesday to block a $10 billion lawsuit Mexico filed against top firearm manufacturers in the U.S. alleging the companies have fueled cartel gun violence. Both liberal and conservative justices appeared skeptical that the claims could clear hurdles in U.

The Mexican government's lawsuit against U.S. gun companies is set to go before the U.S. Supreme Court on Tuesday.
