The political backlash against President Donald Trump is also harming him economically -- which makes him more vulnerable to outside financial interests, one of the few people who has seen Trump's taxes said Thursday on MSNBC.
Tim O'Brien, the author of the 2005 book TrumpNation: The Art of Being the Donald was interviewed by Lawrence O'Donnell on "The Last Word."
"Having seen Trump’s tax returns, having seen this financial disclosure form, what’s the difference?" O'Donnell asked.
"Well, the difference is hundreds of millions of dollars," O'Brien replied.
"And we know from good recent reporting, for example, The Washington Post that the Doral, which is his golf course in Miami and one of his biggest holdings, has been sucking wind for a couple years," he noted. "We know from a recent report in Bloomberg News that Trump Tower is down on its heels."
"The common bond between both properties is they center the Trump brand on them and people are starting to get turned off by that," he explained.
"The larger thing to think about in terms of all of this is if Trump is hurting financially and went into the presidency thinking it was going to help him financially, it only makes him more vulnerable to outside financial influences," he warned.
