Ivanka Trump hosting fundraiser for Cory Booker

The fundraiser will be at Trump's home in Manhattan. Trump is hosting the fundraiser with her husband Jared Kushner and Josh Kushner, Jared's younger brother, according to a source with knowledge of the event.

Trump and Jared Kushner have reportedly raised more than $40,000 for Booker's campaign in the first four months of 2013.

On Thursday, Booker's campaign announced it had raised $4.6 million between April and June 2013.

Recent polls show Booker is the commanding favorite, with a 40-point lead in the Senate race. A Quinnipiac Poll of the New Jersey Democratic primary found 52 percent of registered voters support Booker, followed by Rep. Frank Pallone Jr. with 10 percent support, Rep. Rush Holt with 8 percent and Assembly Speaker Sheila Oliver with 3 percent.

Both Ivanka Trump and her father endorsed Republican nominee Mitt Romney in the 2012 presidential election.
