Both political allies and opponents of Donald Trump are responding with serious concern after possible shots were fired toward the former president at a rally in Pennsylvania. 

President Joe Biden has released a statement about the shooting at Donald Trump's Pennsylvania rally.

I have been briefed on the shooting at Donald Trump’s rally in Pennsylvania.  I’m grateful to hear that he’s safe and doing well. I’m praying for him and his family and for all those who were at the rally, as we await further information. Jill and I are grateful to the Secret Service for getting him to safety. There’s no place for this kind of violence in America. We must unite as one nation to condemn it.

Former President George W. Bush also released a statement saying:

"Laura and I are grateful that President Trump is safe following the cowardly attack on his life. And we commend the men and women of the Secret Service for their speedy response."

"As we await additional information, we are praying for President Trump, his family, our brave law enforcement, and our country," posted Sen. Markwayne Mullin on X.

State Superintendent Ryan Walters has issued the following statement regarding the incident at the rally.

“My thoughts and prayers are with President Trump and his family today after an apparent assassination attempt. While we await additional details on this situation, I know President Trump’s strength and resolve, and know he will not be back down to anyone.”

In a statement, Sen. Blake Cowboy Stephens said:

“My thoughts and prayers are with President Trump following the senseless act of violence that occurred at his rally earlier this afternoon. I am incredibly thankful that he is safe and commend the Secret Service agents who swiftly jumped into action to protect President Trump. Such acts of political violence should never occur on American soil, nor can they be tolerated. As we await more information and reports on the event, I encourage my fellow Oklahomans and Americans to rally around each other and lift our nation up in prayer.”

“I am horrified by what happened at the Trump rally in Pennsylvania and relieved that former President Trump is safe. Political violence has no place in our country,” said Sen. Chuck Schumer in a statement.

Former President Barack Obama said in a statement:

“There is absolutely no place for political violence in our democracy.” He added that while details were still scarce, “we should all be relieved that former President Trump wasn’t seriously hurt, and use this moment to recommit ourselves to civility and respect in our politics.”

The Secret Service says Trump is "safe," after agents rushed him off the stage after what appeared to be multiple shots were fired at the rally. The former president pumped his fist in the air in a show of strength, blood streaming across his face and ear. 

"An incident occurred the evening of July 13 at a Trump rally in Pennsylvania," USSS spokesperson Anthony Guglielmi said in a statement. "The Secret Service has implemented protective measures and the former President is safe. This is now an active Secret Service investigation and further information will be released when available."

"As one whose family has been the victim of political violence, I know firsthand that political violence of any kind has no place in our society," former House Speaker Nancy Pelosi said on X, referencing the attack on her husband, Paul Pelosi. "I thank God that former President Trump is safe. As we learn more details about this horrifying incident, let us pray that all those in attendance at the former president's rally today are unharmed."

"I am horrified by what happened at the Trump rally in Pennsylvania and relieved that former President Trump is safe," Senate Majority Leader Chuck Schumer said in a statement. "Political violence has no place in our country."

"Violence targeted at any political party or political leader is absolutely unacceptable," Pennsylvania Democratic Gov. Josh Shapiro said on X. "It has no place in Pennsylvania or the United States. I have been briefed on the situation. @PAStatePolice are on the scene in Butler County and working with our federal and local partners."

"Political violence is categorically intolerable in American democracy," Democratic Rep. Jamie Raskin, lead impeachment manager during Trump's impeachment proceedings, wrote on X. "We all hope former President Trump is safe and that no one else was injured. We are grateful for the law enforcement response and hope they get to the bottom of this horrifying attack and how it happened."

Trump's estranged former vice president, Mike Pence, posted on X, "Karen and I are praying for President Trump and urge every American to join us."

Former President George W. Bush expressed gratitude that Trump is safe as well, thanking law enforcement. 

"Laura and I are grateful that President Trump is safe following the cowardly attack on his life," Bush wrote. "And we commend the men and women of the Secret Service for their speedy response." 

Republican Sen. J.D. Vance of Ohio, one of Trump's potential picks for vice president, wrote on X, "Everyone join me in praying for our President Trump and everyone at that rally. I hope everyone is ok."

House Speaker Mike Johnson said he has been briefed on the incident, condemning "this horrific act of political violence." 

"Kelly and I are praying for President Trump and all the attendees of the campaign rally today in Pennsylvania, and we send our gratitude to the law enforcement who responded at the scene," Johnson wrote on X. "I have been briefed by law enforcement and am continuing to monitor the developments. This horrific act of political violence at a peaceful campaign rally has no place in this country and should be unanimously and forcefully condemned."

Republican Sen. Lindsey Graham of South Carolina, one of the president's most ardent supporters in the upper chamber, also pointed to prayer. 

"Thank God President Trump seems to be okay," Graham wrote on X. "Just another reminder of the times in which we live. We need to pray fervently for anyone who may have been injured at the rally."
