People close to Donald Trump are reportedly scrambling to come up with a political strategy to save his campaign after last week's mass shooting in Orlando failed to give the candidate a "bump in the polls" as his aides had hoped.

According to a report published by Bloomberg on Monday, top campaign officials and members of Trump's family were gathering in New York in an effort to get the presumptive Republican nominee back on track after a series of missteps following the shooting at Pulse nightclub in Orlando.

"The frustration among Trump's allies increased after his speech last week in Manchester, N.H., where he responded to the mass shooting at an Orlando nightclub," Bloomberg reported. "Many in Trump's inner-circle had predicted that he would get a bump in the polls, as he did following the terror attacks in Paris and San Bernardino, Calif. Instead, he faced a well-orchestrated rapid response machine from the Clinton campaign and the Democratic Party, which hammered him for days."

The New York Times confirmed on Monday that Trump had once again reshuffled the roles of his top advisers, and that controversial Campaign Manager Corey Lewandowski would be leaving.

"The Donald J. Trump Campaign for President, which has set a historic record in the Republican primary having received almost 14 million votes, has today announced that Corey Lewandowski will no longer be working with the campaign,” the campaign explained in a statement. “The campaign is grateful to Corey for his hard work and dedication and we wish him the best in the future.”
