A review of billionaire Republican presidential candidate Donald Trump's financial records finds that he has donated considerably less to charity than others in his tax bracket and has also taken credit for charitable gifts made by others.

Claims, made by Trump, that he has donated $102 million to charity in cash and land over the last five years fall short. An Associated Press report hints that in one instance, a land donation, which Trump is set to receive a huge tax deduction for, actually serves as a golf driving range.

In addition, his campaign has provided little documentation of many of those alleged contributions, and tax filings from the Donald J. Trump Foundation indicate he hasn't made a contribution to his own namesake nonprofit since 2008.

"I give to hundreds of charities and people in need of help," Trump said in an emailed response to questions from the AP about how he tallied his own philanthropy. "It is one of the things I most like doing and one of the great reasons to have made a lot of money."

Still, the campaign has been slow to respond to direct requests that the candidate provide tangible evidence of donations directly given. Trump has yet to release his personal tax records.

Trump's foundation was formed in 1987, yet still has no staff, and in IRS filings the amount of time Trump dedicates to the agency is listed as "minimal." The foundation gave out $3.6 million between 2011 and 2013, the most recent year in which its finances are available.

Up until 2014, or shortly before he publicly announced his run for the Oval Office, Trump was described as an "ardent philanthropist" in a biography posted to the Trump Organization's website. That language has since been removed.

Trump's tax returns would provide clearer information about any philanthropy he listed as deductible. Years ago, he indicated he might be willing to release his own tax returns if President Obama produced his birth certificate. Since then, the president has held up his part of the agreement, but Trump has only committed to doing so at "the appropriate time."
