Sources consistently place two members of Oklahoma’s congressional delegation, Kevin Hern and Markwayne Mullin, in the top 10% of all 535 members of Congress based on net worth. 

Using personal financial disclosure reports from 2018, OpenSecrets ranked members of Congress by approximate net worth by adding each disclosed asset value range and subtracting the liability value range, placing Hern and Mullin at No. 12 and No. 45, respectively. 

Quiver Quantitative, which uses live data on politicians’ stock portfolios made available through the STOCK Act, currently ranks Hern and Mullin at No.10 and No. 16, respectively. 

Though OpenSecrets also includes data filed under the STOCK Act, which requires members of Congress to report all financial transactions after they occur, only Quiver Quantitative is regularly updated. 

OpenSecrets estimated the 2018 net worths of Hern and Mullin to have been about $61 million and $11 million, respectively, while Quiver Quantitative has current estimates of $106.76 million and $65.04 million, respectively.
