Apple CEO Tim Cook is hosting a fundraising breakfast for House Speaker Paul Ryan at an undisclosed location in Menlo Park today.

Apple Treasurer Gary Wipfler is also taking part in the event to raise money for Rep. Ryan, R-Wisconsin, and a joint fundraising committee aiming to elect more Republicans to the House of Representatives, Politico.com reported.

The U.S. Capitol Police is leading on the security for the event, but Menlo Park will provide assistance "when and if necessary," said Menlo Park Police Department spokesperson Nicole Acker.

According to Politico, Apple does not have a corporate political action committee and Mr. Cook is hosting the event on his own. Apple backed out of supporting the Republican National Convention after Donald Trump became the presumptive GOP presidential nominee.

Mr. Cook has donated to both Democrats and Republicans in the past.
