California US Rep. Mark DeSaulnier is in critical condition with noncoronavirus pneumonia after he fell during a run in the nation’s capital, his chief of staff announced.

DeSaulnier, 67, was hospitalized March 13 with complications from pneumonia after he suffered a rib fracture, according to a statement posted on Twitter Saturday by the Bay Area Democrat’s chief of staff, Betsy Arnold Marr.

It’s unclear exactly when DeSaulnier (right) took the spill.

“Unfortunately, Congressman DeSaulnier’s condition has deteriorated and he is in critical condition,” the statement said. “The doctors are doing everything they can to care for the Congressman.

“Mark’s family and staff appreciate your thoughts and prayers during this difficult time.”

When, DeSaulnier was admitted, he was in “serious, but stable condition” and expected to hospitalized for “at least the next several days,” the San Francisco Chronicle reported at the time.

The congressman has also tested negative for the coronavirus.

DeSaulnier’s COVID-19 test was conducted “out of abundance of caution . . . it was purely a box check,” Marr said.

While hospitalized, DeSaulnier on March 14 missed the House’s vote on a coronavirus aid package.

The bipartisan relief package nevertheless easily passed both chambers of Congress and was signed into law by President Trump on Wednesday night.

The relief bill would provide free testing and two weeks’ paid sick leave for full-time workers who fall ill with COVID-19.

The bill also provides $1 billion in food aid to the needy and $1 billion in unemployment funds to states —as the number of US coronavirus cases soared to more than 30,000 on Sunday.

DeSaulnier was elected to congress in 2014 after serving as a state senator and assemblyman in his state, according to his official biography.

The lawmaker serves on numerous committees, including the Education and Workforce Committee and the Committee on Oversight & Government Reform’s subcommittee.
