Texas homebuilder and noted political donor Bob Perry has died at the age of 80.

According to a report from The Dallas Morning News, Perry died in his sleep on Saturday night or Sunday morning at his home in Houston. The cause of the death has not been released

In the late 1960s, Perry started a homebuilding business in Houston called Perry Homes. The company is now one of the largest home builders in the U.S.

With the success of Perry Homes, Perry became wealthy, and used his wealth to support conservative political causes. He was a major donor for both George W. Bush and Rick Perry (no relation) during their campaigns for Governor of Texas. Perry was also reportedly donated over $900,000 to the Texas Republican Party in 2002.

During the 2004 election, Perry was the largest single donor to the 527 group Swift Boat Veterans for Truth, donating over $4.4 million to the group. Since that time, Perry has donated millions to organizations dedicated to electing Republican candidates, including 2012 presidential candidate Mitt Romney.
