The federal courthouse and building in Midland, Texas, is about to be named for the two Bush presidents who once called the West Texas city their home.

The Senate gave final approval Tuesday to legislation that would re-designate the facility after George H.W. Bush and his son George W. Bush. The bill heads to President Obama's desk for his signature.

"It's my distinct honor to help preserve the legacy of two great leaders and Texans as they continue to leave their mark on this nation, and I cannot think of a better way to do that than by memorializing them in Midland," said Sen. John Cornyn, R-Texas.

Cornyn pushed for the name change with Rep. Mike Conaway, who represents Midland in the House.

The elder Bush, the 41st president, made his fortune at an oil company he founded in Midland and later moved to Houston. The younger Bush, the 43rd president, spent his formative years in Midland and tried to launch his political career there with a race for Congress. George W.'s childhood home on West Ohio Street is now a museum dedicated to both presidents.

The federal facility in Midland has carried the name of the late congressman George Mahon, who served 22 terms in the House and chaired the Appropriations Committee for years.

It's official name will be a mouthful: The George H.W. Bush and George W. Bush United States Courthouse and George Mahon Federal Building.
