Hillary Clinton will get a helping hand at a fundraiser in Omaha, Nebraska, Monday from deep-pocketed investor Warren Buffett — the third billionaire in less than a week to jump to the Democratic presidential nominee’s aid.

The two will hold a public rally together at Omaha North High Magnet School, where Clinton “will discuss her commitment to building an economy that works for everyone, not just those at the top,” according to the Clinton campaign.
