Both Presidential contenders are reacting to the deadly police shootings in Dallas last night.

FOX's Jon Decker has more from the White House:

Hillary Clinton has taken to Twitter to write that she mourns for the officers shot while doing their sacred duty to protect peaceful protesters, for their families and all who serve with them.

She's cancelled a campaign event in Scranton, Pennsylvania with Vice President Biden, but will still address a religious convention in Philadelphia. 

Republican Donald Trump has cancelled a trip to Florida. He put out a statement saying that last night's horrific execution-style shootings were an attack on our country. He also wrote that this is a time, perhaps more than ever, for strong leadership, love and compassion.

At the White House, Jon Decker, FOX News.
