Celebrity Dallas Police Shooting: Hillary Clinton and Donald Trump Cancel Campaign Events, George W. Bush 'Heartbroken' by Attack in His Home City Donald Trump called the shootings a "coordinated, premeditated assault on the men and women who keep us safe" By Tierney McAfee Published on July 8, 2016 12:10 PM Share Tweet Pin Email Photo: Getty (2) Donald Trump and Hillary Clinton both canceled campaign events on Friday in the wake of the shooting at a Black Lives Matter protest in Dallas Thursday night that killed five police officers. Clinton postponed her rally in Scranton, Pennsylvania, at which Vice President Joe Biden was expected to appear and endorse the presumptive Democratic nominee. The former secretary of state spoke out about the shootings on Twitter, saying, “I mourn for the officers shot while doing their sacred duty to protect peaceful protesters, for their families and all who serve with them.” She plans to address the attack in a speech later Friday at the AME National Convention in Philadelphia. Trump, meanwhile, released a statement calling the “horrific execution-style” shootings a “coordinated, premeditated assault on the men and women who keep us safe.” He also weighed in on the “senseless, tragic” fatal police shootings of Alton Sterling and Philando Castile in Louisiana and Minnesota earlier this week. “Our nation has become too divided,” Trump said. “Too many Americans feel like they’ve lost hope. Crime is harming too many citizens. Racial tensions have gotten worse, not better. This isn’t the American dream we all want for our children.” REALTED VIDEO: Snipers Kill Five Officers at Dallas Protests Trump also tweeted about the attack early Friday morning and again several hours later: Former President George W. Bush and wife Laura Bush, who live in Dallas, released a statement Friday saying, “Laura and I are heartbroken by the heinous acts of violence in our city last night. Murdering the innocent is always evil, never more so than when the lives taken belong to those who protect our families and communities.” Bush went on to praise the “dedication, professionalism, and courage of the Dallas Police Department” and offer condolences to the “families of the fallen.” “We pray for the wounded officers to recover fully and quickly. We commend Mayor Rawlings, Chief Brown, and all our city’s leaders and public servants who continue to organize an effective response to this tragedy. And we join our fellow citizens in saluting the fine law enforcement officers in Dallas and across the country who put their own lives on the line to keep all lives safe.” Other politicians also took to social media to condemn the shootings in Dallas. Vermont Sen. Bernie Sanders denounced the shootings as “horrifying and despicable” and called for “an immediate investigation with the Department of Justice.” House Speaker Paul Ryan called for “justice” and “healing” after the attack. President Obama also condemned the shootings during a NATO summit in Warsaw, Poland, calling them a “vicious, calculated and despicable” attack on law enforcement. “I believe I speak for every single American when I say we are horrified over these events, and we stand united with the people and the police department in Dallas,” the president said. “Police in Dallas were on duty doing their jobs keeping people safe during peaceful protests,” he added. “Let’s be clear: There is no possible justification for these kinds of attacks or any violence against law enforcement.”
