(Bloomberg) -- Elizabeth and Richard Uihlein, the billionaire shipping magnates who are among President Donald Trump’s biggest donors, have tested positive for the coronavirus, according to an email seen by Bloomberg News.

Elizabeth Uihlein, the chief executive officer of shipping-supply company Uline Inc., announced her illness in a memo sent to her more than 6,000 employees on Wednesday afternoon.

“After all these long months, I thought we’d never get it,” she wrote. “Well, Trump got it... If we had not been around people with COVID, we would not have been tested.”

The Uihleins, who Bloomberg estimates are worth around $4 billion, are outspoken Republicans and have donated tens of millions of dollars to Trump and conservative causes in recent years. This spring, Elizabeth Uihlein criticized the lockdown mandates and encouraged her employees to sign a petition to unseat Wisconsin Governor Tony Evers, a Democrat.

Richard Uihlein is chairman of the company.

In a statement, Uline said the company doesn’t disclose health information about specific employees, citing health privacy law.

“Uline has instituted numerous changes to normal operating policies to respond to COVID-19 with health and safety in mind,” the company said. “As we are made aware of positive cases among Uline personnel, we continue to promptly notify others who may be exposed to the virus, so the proper protocols can be quickly put into place.”

The Uihleins’ infections were reported earlier by Patch.com.
