PALO ALTO – Facebook Inc has seen an increase in signals indicating potential future acts of violence associated with efforts to contest the result of the U.S. presidential election since the Capitol siege last week, a company spokeswoman told Reuters.

The spokeswoman, who asked not to be named for security reasons, said late Tuesday the storming of the U.S. Capitol by armed pro-Trump demonstrators appeared to be a galvanizing event, spawning efforts to organize gatherings across the country for multiple dates around President-elect Joe Biden’s Jan. 20 inauguration.
