The former CEO of consumer products giant Procter & Gamble says he has had it with his longtime Republican party.

Pepper, who grew up a Republican and had been a longtime Republican donor, wrote on his blog "Pepperspectives" this week that he no longer recognizes the party.

When will, I ask, responsible Republicans return to the principles that marked the Republicans I respected? When will they stop standing aside to let the meanness and cruelty and lying and rumor-mongering of Donal Trump go unchallenged? When will they again insist that their candidates, especially for the Presidency, embody the highest values of our nation. starting with integrity and respecting the dignity of everyone.

Pepper was CEO of P&G from 1995 to 1999. He is also a former chairman of both P&G and The Walt Disney Co.

Pepper's announcement is not entirely unexpected.

His son, David, chairs the Ohio Democratic Party.

While he had been a Republican donor in decades past, his most recent donation to a Republican at the federal level appears to have been in 2015. He was a frequent donor to Democrats after that, including 2016 Democratic presidential candidate Hillary Clinton, according to the Center for Responsive Politics.

Voting records show he has voted in Democratic primaries in recent years.
