House Speaker Emerita Nancy Pelosi, D-San Francisco, is the latest member of Congress to receive a suspicious letter at her district office after similar cases have been reported recently elsewhere involving a powdery substance sent to congressional offices around the Bay Area and nation.

Pelosi’s San Francisco district office received the letter Wednesday and her office said it was “consistent with mailings reported by other congressional offices around the country.”

U.S. Reps. Mike Thompson, Mark DeSaulnier and Jimmy Panetta are among the other local members of Congress who reported receiving the letters in the past week.

The office of Thompson, D-St. Helena, said earlier this week that U.S. Capitol Police have tested the powder sent to other congressional leaders and determined it was not hazardous.

According to Pelosi, everyone in her office was safe after receiving Wednesday’s letter.

“Speaker Pelosi remains focused on serving the people of San Francisco and is concerned for the members and staff whose offices have experienced similar incidents. She is grateful for the efforts of the U.S. Capitol Police, the San Francisco Police Department and other law enforcement agencies to thoroughly investigate this series of intimidation across America,” Pelosi said in a statement.
