CHEYENNE, Wyo. (AP) — Sen. Mike Enzi is standing by recent votes against raising the federal debt limit.

He says lawmakers and President Barack Obama need to have a plan to get federal spending and the national debt under control.

Enzi said in an interview Wednesday with The Associated Press that interest alone on the debt is on track to surpass current military spending. The Congressional Budget Office estimates such payments could reach $880 billion annually in 10 years.

Last week, Texas Sen. Ted Cruz sought to filibuster raising the debt limit. That meant the measure needed not a simple majority but at least 60 votes to move ahead.

Enzi and Cruz voted twice against raising the debt ceiling, even though not raising the limit could have shut down the federal government.
