WASHINGTON (AP) — The Republican-controlled Senate is moving ahead on a bill to construct the Keystone XL pipeline despite President Barack Obama's veto threat.

A test vote was scheduled for late Monday, though winter weather could delay the roll call.

The legislation would authorize construction of the 1,179-mile pipeline. It would carry more than 800,000 barrels of crude oil a day from Canada to refineries along the Texas Gulf Coast.

The House approved the bill last Friday. Senate Republicans back the measure, arguing that it will create thousands of jobs. It's expected to attract the support of several Democrats.

The White House has threatened a presidential veto of the measure, saying it conflicts with longstanding presidential authority and his ability to make decisions on issues in the nation's interest.
