The Daily Beast: 11 Private Security Firms Guarding Donald Trump
“A security expense that Mr. Trump was incurring before running for president is an expense that did/would exist irrespective of his campaign for president and, therefore, would constitute an illegal personal use of campaign funds,” said Paul Ryan of the Campaign Legal Center.
“A strong argument could be made that using campaign funds to pay this longtime personal security guard is illegal personal use of campaign funds. However, the FEC has historically been a little more lenient with the personal use ban with matters of health and security… There might be some special circumstances for Mr. Trump, but if I were him I would have gone to the FEC for an Advisory Opinion before beginning to pay for arguably personal security services with campaign funds.
