Regis Philbin did not leave $20 million to the Trump campaign.
Research shows that Philbin has not donated to the Trump campaign. Records from the Federal Election Commission indicate that Philbin has given to elections twice, once to a republican candidate, and once to a democratic one between 2008-2012. However, there is no evidence for his donation to the Trump Campaign in recent years.
Therefore, Regis Philbin has not left $20 million to the Trump campaign.
