Missed this story (and the Illinois one Derek flags) while traveling:

Representative Henry Cuellar, a Texas Democrat in a crucial swing district, and his wife were charged with participating in a yearslong $600,000 bribery scheme involving Azerbaijan and a Mexican bank, according to a federal indictment unsealed in Houston on Friday.

The accusations against Mr. Cuellar, 68, and his wife Imelda, 67, center on allegations of bribery and money laundering in connection with their efforts on behalf of an oil and gas company owned by Azerbaijan’s leaders as well as an unnamed bank based in Mexico City, according to the 54-page complaint.

Mr. Cuellar, a Laredo native first elected in 2004, is also accused of acting as an agent of a foreign entity while a U.S. government official — by delivering a speech favoring Azerbaijan in Congress and inserting provisions into aid bills to benefit those who were paying bribes to his family.

I wonder how a Speech or Debate Clause defense might figure into claims based on delivering a speech in Congress.
