From the above article:
In one text written in 2015, Ms. Manafort, a lawyer, called her father’s activities in Ukraine “legally questionable,” and in a separate exchange with her sister, Jessica, she worried that cash he gave them was tainted by the violent response to the uprising that ultimately led to the downfall of Mr. Manafort’s client, Mr. Yanukovych.
“Don’t fool yourself,” Ms. Manafort wrote. “That money we have is blood money.”
