Missouri governor Eric Greitens—charged with a sexual felony, accused of campaign finance crimes, approval rating underwater, impeachment a strong possibility—could be nearing the end of his political career. But the Republican appears to be set on taking as much of his own party with him as possible, beginning with his attorney general—and U.S. Senate contender—Josh Hawley.

Over the last few weeks, Greitens has pursued an aggressive campaign to discredit Hawley, whose office is among those investigating the governor’s misconduct. Greitens launched his first attack on April 17, after Hawley announced he had uncovered evidence that Greitens had, in addition to his sexual misconduct, committed a campaign-finance-related crime.
