Police in the nation's capital are bringing in additional officers and mobilising in anticipation of growing protests outside the US Supreme Court.
The court issued a highly charged decision that ends constitutionally protection to abortion nearly 50 years after Roe v. Wade made abortion legal.
US Capitol Police says it has been working closely with other law enforcement agencies in order to prepare for demonstrations.
A law enforcement official says the department is mobilising its civil disturbance unit and also bringing on additional officers on Friday.
The official could not publicly discuss details of the internal security procedures and spoke to The Associated Press on condition of anonymity. Hundreds of people had already descended outside the court after the ruling was handed down on Friday.
