This story has more relavance if you know what state they are in. In this case Washington State, bit I had to go digging for the information. Even the NY Post only obliquely referred to Washington. I did not know if which they meant. In doing so I went to wiki to find she has wiki imortality. But I was surprised to see this additional information.
Mary Katherine Schmitz was born in Tustin, California, the daughter of Mary E. (née Suehr), a chemist, and John G. Schmitz, a university professor.
When she was two years old, her father began his political career and successfully ran as a Republican for a seat in the state legislature. He held positions as a California state senator and U.S. Congressman, winning a special election for an unexpired term in 1970 and the general election later that year. After a primary defeat in 1972, he changed parties and ran for president as an ultra-conservative American Independent Party candidate in the 1972 U.S. presidential election.
In 1978, her father was elected once again as a Republican to the California State Senate. He intended to run for the U.S. Senate in 1982, but his political career was permanently damaged that year when it was revealed that he had fathered two children out of wedlock during an affair with a former student at Santa Ana College, where he had taught political science.
Her brother John Patrick Schmitz was the deputy counsel to President George H. W. Bush. Her other brother, Joseph E. Schmitz, was Inspector General of the U.S. Department of Defense under George W. Bush, was a senior executive with Blackwater Worldwide, and is a foreign policy adviser to President Donald Trump.
You forgot the part about “When her little brother was 5, Mary allowed him to accidentally drown in the family swimming pool”.
