Preserve digital evidence of Capitol riot: US Senator to Zuckerberg
US Senator Mark Warner has written to Facebook CEO Mark Zuckerberg, asking him to "preserve any and all posts" that may be associated with Wednesday's attack on US Capitol. Efforts to bring perpetrators to justice will involve "digital evidence", he added. He also urged Zuckerberg to "undertake reasonable measures" to identify content that may be needed for future legal action.
