Breitbart notice the coincidence too on March 13th.
"January 15: Speaker of the House Nancy Pelosi (D-CA) holds a vote to send articles of impeachment to the Senate. Pelosi and House Democrats celebrate the “solemn” occasion with a signing ceremony, using commemorative pens.
That same day, the first person with coronavirus in the United States arrives from China, where he had been in Wuhan."
