WASHINGTON (WJW) — Legislators, including Ohio Rep. Tim Ryan, are speaking out in wake of the deadly attack at the U.S. Capitol.

Rep. Ryan held a press conference Friday after a man rammed a car into two officers at a barricade outside the U.S. Capitol and then emerged wielding a knife. Officer William “Billy” Evans was killed during the incident and another officer was injured.

During the briefing Ryan said he expects that officials will review the incident and security protocols at the Capitol. He shared that security concerns have been active topics of conversation among lawmakers since the Jan. 6 riots that occurred at the Capitol.

The Congressman shared that the latest attack “continues to provide a level of uncertainty and worry about the workplace.” However, Ryan explained that the U.S. is actively researching new ways to increase security.

“It is going to take a bipartisan effort,” he argued. “This is about the security of the nation’s Capitol, that’s the temple of democracy. We’ve got to make sure that it is secure.”

Ryan says that he, along with other several legislators, wants to increase Capitol police staffing by close to 1,000 new officers. Lawmakers have also extended the perimeter around the Capitol and are working to increase intelligence efforts so that attacks can be foiled before they are acted on.

“That’s where we need to be and we aren’t there yet,” he said. “We have to be very careful until we get there.”

Ryan expects that all security measures will be re-evaluated in wake of the attack.

The Congressman also issued his support to the Capitol Hill and Capitol Police families saying “today was another blow.”

Several lawmakers have spoken out in wake of the attack.

“This is heartbreaking. My prayers are with the officer’s family, friends, and colleagues on the USCP force. God bless the US Capitol Police,” Sen. Rob Portman shared on Twitter.

Rep. Marcy Kaptur issued a statement on Twitter reading, “This is a horrific tragedy. My prayers are with the family of the officer killed in the line of duty and the officer who was injured. It has been a devastating year for the Capitol Police and those who serve in the Capitol. They are in my heart today.”

“I’d ask everyone to join me in prayer for the soul of our fallen Capitol Police officer who lost their life in the line of duty today as well as the entire USCP family. These brave men and women put their lives on the line every day and they need our support now more than ever,” Rep. Anthony Gonzalez shared.

U.S. Sen. Sherrod Brown released the following statement to FOX 8:

“I’m deeply saddened by the news that a U.S. Capitol police officer has died today as a result of another violent attack on our nation’s capital. Our hearts and prayers are with the officer’s family and friends, as well as the other officer injured in the attack. My office will continue to closely monitor the situation and offer any assistance we can to help keep our law enforcement officials — and the public they serve — safe.”

Earlier Friday, Ryan issued his condolences to Officer Evans’ loved ones on Twitter saying, “my thoughts and prayers are with their family.”

The suspect, who has not yet been identified, was shot by authorities and died at a hospital. Police say the attack did not appear to be related to terrorism, though the Capitol was put on lockdown as a precaution, and there isn’t an ongoing threat.

This attack remains under investigation. FOX 8 will provide more information as government officials release it.
