Security fencing surrounded the US Capitol on Thursday, 7 March, ahead of Joe Biden’s State of the Union address. A sign reading “Police line. Do not cross” was visible on the perimeter. It is the fourth time such a security measure has been taken for a State of the Union speech in the aftermath of the insurrection at the Capitol on January 6 2021. It comes as Donald Trump is charged with crimes connected to efforts to overturn the results of the 2020 election.
