From a Washington Post Retropolis column by Frederic J. Frommer headlined “Could Pence turn on Trump? Here’s how Ford finally broke with Nixon”:

The subpoena issued to Mike Pence this week by the special counsel investigating Donald Trump’s failed bid to overturn the 2020 presidential election could irreparably sever relations between the former president and his onetime loyal vice president, if it causes Pence to testify against his old boss.

A half-century ago, Vice President Gerald Ford also faced a tipping point in his relationship with Richard M. Nixon, and decided to break with the beleaguered president.
