COLUMBIA, S.C. (AP) — The governors of North and South Carolina are among top Republicans imploring the president not to veto a bill to build the Keystone XL oil pipeline.

South Carolina Gov. Nikki Haley and North Carolina Gov. Pat McCrory on Thursday signed a letter asking President Barack Obama not follow through on his threat to veto the measure.

The letter was signed by 24 Republican governors who say the pipeline would create thousands of jobs and strengthen the United States' relationship with Canada.

On Wednesday, the Republican-controlled Congress approved a bill to construct the Keystone XL oil pipeline.

Neither the House nor the Senate has enough votes to override a veto, the first of many skirmishes between the Democratic White House and Congress on energy and environmental policy.
