An overconfident attitude that they can handle anything is hampering the efforts of the Secret Service, including keeping GOP presidential front-runner Donald Trump as safe as possible, author Ronald Kessler tells Newsmax TV. Even after a Friday night protest in Chicago caused Trump to cancel his rally there and a protester stormed the stage the next day in Ohio, the Secret Service isn't likely to take action to make Trump safer, Kessler told "Newsmax Prime" on Monday.Watch Newsmax TV onandGet Newsmax TV on your cable system — Click Here Now "The Secret Service management is very arrogant, that's why we've seen one example of laxness after the other," said Kessler, author of "The First Family Detail." The Secret Service has "a cover-up mentality," he added, "and they're simply not going to make changes or urge him fervently to be more careful and impose more precautions."While it's hard to imagine why the Secret Service would be like that, he said, "we've seen that over and over again, and they're going to take the attitude that we are the great Secret Service, we can handle anything."The agency will not provide sufficient protection, Kessler said, "and that is a serious danger."Economist Peter Morici, who also appeared on the program, told host Ed Berliner that candidates should have the protection that they need, not necessarily what they "deserve.""In this circumstance, Donald Trump needs more protection because he's simply more of a phenomenon than say Mr. [Marco] Rubio or even Mr. [John] Kasich."Kessler said Trump's positions, regardless of whether you agree with them, stir up passions in people, and that should be making the Secret Service even more vigilant.Nothing has significantly changed in the Secret Service's attitude since the 2009 White House gate-crashing by Michaele and Tareq Salahi, Kessler said."The Secret Service management has this attitude that they're invincible," he said. "It's not the agents themselves. They're brave and dedicated. But the management has this culture, you saw the result when an intruder was allowed to penetrate the White House itself, he was armed, in September 2014."Spectators should not be allowed behind or around Trump, he said, and he should have an armored podium.Trump should probably give up public rallies if he secures the Republican nomination because he gets enough exposure on television, Kessler said.The Islamic State (ISIS) "would like nothing better than to wipe him out with WMD," Kessler said. "They have billions of dollars being paid to scientists to develop weapons of mass destruction; they could wipe him out, they could wipe out thousands of spectators by just strolling in, as well as domestic assassins."
