Republican presidential contender Jeb Bush will release not only his third-quarter fundraising numbers Thursday, which is the deadline for campaigns to report their quarterly finances, but the former Florida governor will also list his campaign bundlers, 2014 tax returns and medical records, Fox News has learned.

The Bush campaign is calling the move an effort of unparalleled transparency.

“Jeb Bush remains the most transparent candidate in the entire presidential race,” Bush senior aide Kristy Campbell told Fox News on Wednesday. “Tomorrow's donor disclosure is a first in the Republican field and follows his previous unprecedented release of nearly 300,000 emails from his time in public office and 33 years of tax returns. This display of transparency is consistent with the high level of disclosure he practiced as governor of Florida, and, frankly, should be expected of those seeking the nation's highest office.”
