Donald Trump may get an intervention from Newt Gingrich, Rudy Giuliani and other supporters

Republican presidential nominee Donald Trump has had a whirlwind week. From relentlessly attacking the family of a dead U.S. soldier to refusing to endorse House Speaker Paul Ryan or Sen. John McCain's primary races (and even praising Ryan's primary challenger), Republicans are concerned about Trump's campaign. Republican National Committee Chairman Reince Priebus is reportedly not pleased.

Republicans who have endorsed Trump, such as former New York City mayor Rudy Giuliani and former House Speaker Newt Gingrich, are meeting in an attempted campaign intervention. They hope to include Trump’s children in the conversation, as they are influential in their father’s campaign.

When Ryan initially cited Trump's behavior as one of the reasons why he was not ready to back Trump, the presidential nominee shamed him on Twitter.

Ryan joined McCain and Senate Majority Leader Mitch McConnell to disavow Trump's attacks on the Khan family, whose son died while serving in Iraq.

“America’s greatness is built on the principle of liberty and preserved by the men and women who wear the uniform to defend it,” said Ryan. Without mentioning Trump by name, Ryan said that Capt. Khan and his family’s sacrifice “should always be honored. Period.”

Ryan recently said Republicans needed to take the high, moral ground. He said doing so “will help us retake the soul of our own party, which we have our own challenges with these days.”
