Actor Chuck Norris, baseball legend Roger Clemens and at least 14 Bush family members are rallying behind Republican Pierce Bush in one of the nation’s hottest congressional primaries.

Campaign finance reports released Friday showed Bush has raised more than $663,000 during his first month in the race for the Houston area’s 22nd Congressional District. Nearly 10 percent of that money came from his famous family, including donations of $2,800 each from former President George W. Bush and former First Lady Laura Bush.

Pierce Bush, the 33-year-old CEO of Big Brothers Big Sisters Lone Star, has also won support from Houston Rockets owner Tilman Fertitta and former Astros CEO Drayton McClane Jr.

This is the first bid for public office for Pierce Bush, the grandson of former President George H.W. Bush.

Despite all the family backing, Pierce Bush is still a financial underdog in the 15-person GOP primary for the 22nd District. Republican Kathaleen Wall donated another $1 million of her own money to her campaign over the last three months and now has put in a total of $1.6 million, according to the latest reports filed with the Federal Election Commission.

It’s not the first time that Wall, a longtime GOP donor, has run a campaign with her own money. She spent $6.2 million of her own money to run for the nearby 2nd Congressional District in 2018, but lost that race in a primary to eventual winner Dan Crenshaw.

Fort Bend Sheriff Troy Nehls, who launched his campaign in early December, has raised just over $200,000.

Former Pearland City Councilman Greg Hill had raised over $217,000 through October, but his latest campaign finance report had not been posted by the Federal Election Commission as of Friday night.

No other candidates in the crowded field for the March 3 Republican Primary reported more than $200,000 of funding.

The candidates are battling for the 22nd Congressional District, which includes most of Fort Bend County and parts of northern Brazoria and southern Harris counties. U.S. Rep. Pete Olson, R-Sugar Land, announced in 2019 he would not seek re-election, setting the stage for the crowded GOP primary race.

But the district is also one of the Democrats’ top targets in Texas.

Democrat Sri Preston Kulkarni came within 5 percentage points of beating Olson in 2018. Kulkarni is running again, but faces three other Democrats in a primary on March 3.

Kulkarni has the most financial support on the Democratic side. He’s raised about $1.1 million for his campaign. Former Pearland City Councilman Derrick Reed’s latest reports were not available as of Friday, but Reed had raised $114,000 as of Oct. 1, 2019. Attorney Nyanza Davis Moore has raised just over $142,000. Retired electrician Carmine Petrillo III had not reported any fundraising as of Friday.
