Donald Trump Wants to 'Restore Law and Order' After Week of Police-Involved Shootings

Clinton and Trump postpone their events in the wake of the Dallas ambush.

— -- Presumptive Republican presidential nominee Donald Trump weighed in this morning on the shootings of the past few days, describing the Dallas shooting of police officers as "horrific," calling for law and order to be restored and offering his "thoughts and prayers for all of the victims’ families."

"Last night’s horrific execution-style shootings of 12 Dallas law enforcement officers – five of whom were killed and seven wounded - is an attack on our country," Trump said in a statement released this morning. "It is a coordinated, premeditated assault on the men and women who keep us safe."

Seven police officers were injured and five were shot dead in Dallas Thursday night by at least two snipers, amid a protest against the recent police shootings of two black men, Alton Sterling in Louisiana, and Philando Castile in Minnesota, according to the Dallas Police.

"The senseless, tragic deaths of two motorists in Louisiana and Minnesota reminds us how much more needs to be done," Trump said, referring to Sterling and Castile, both black men who were shot and killed by white police officers this week.

Sterling was fatally shot Tuesday while selling CDs outside a Baton Rouge convenience store. Castile was killed during a traffic stop Wednesday night in the Saint Paul, Minnesota, suburb of Falcon Heights.

"We must restore law and order. We must restore the confidence of our people to be safe and secure in their homes and on the street," Trump said in the statement.

Trump also tweeted, offering "prayers and condolences" to the families.

Trump has canceled his trip to Miami in the wake of the shooting in Dallas.

Presumptive Democratic nominee Hillary Clinton tweeted today that she "[mourns] for the officers shot while doing their sacred duty to protect peaceful protesters."

In light of the Dallas shooting of multiple police officers Thursday night, Clinton has also postponed her planned campaign event with Vice President Joe Biden in his hometown of Scranton, Pennsylvania.

Clinton is still expected to deliver remarks today about the deaths of Sterling and Castile at the African-Methodist Episcopal Convention in Philadelphia, according to a Clinton campaign official.

Bernie Sanders, who in the past few days has been tweeting consistently in support of federal investigations into the deaths of Alton Sterling and Philando Castile, this morning also tweeted about Dallas.
