Billionaire David Koch is stepping away from Koch Industries and the the Koch political network due to his poor health, leaving his brother, Charles, at the helm.

Why it matters: The Koch network has received considerable attention for its role in the rise of what the left calls “dark money,” with their donations funding substantial portions of conservative activism. The Koch brothers have also played a major philanthropic role in the U.S., and the David H. Koch Foundation alone has pledged or contributed more than $1.3 billion to cancer research, medical centers, educational institutions, and arts and cultural institutions.

"Due to health reasons, David Koch will be resigning from the board of Americans for Prosperity Foundation. We greatly appreciate his vital role on the board and all that he has done to help us build a strong foundation for our future success. We wish him and his family well.”
— The Seminar Network Co-chairman Mark Holden

Take note: Despite the announcement, David has had a minimal role in recent years and Charles has steering the network.

Texas AG sues Biden administration over deportation freeze

Texas Attorney General Ken Paxton is suing the Biden administration in federal district court over its 100-day freeze on deporting unauthorized immigrants, and asking for a temporary restraining order.

Between the lines: The freeze went into effect Friday, temporarily halting most immigration enforcement in the U.S. In the lawsuit, Paxton claims the move "violates the U.S. Constitution, federal immigration and administrative law, and a contractual agreement between Texas" and the Department of Homeland Security.
