Donald Trump’s three oldest children have campaigned with their father and served as surrogates during the presidential race. But only one of them is actually a member of the party Trump hopes to lead.

Records from the New York State Board of Elections show that neither Ivanka Trump nor Eric Trump is enrolled in a political party. Trump’s oldest son, Donald Trump Jr., is a Republican.

Both Eric and Ivanka Trump have also donated money to Democrats. Campaign finance reports show Eric gave $1,000 to Sen. Chuck Schumer, D-N.Y., in 2010. Eric has made 11 other contributions totaling over $138,000 that all went to Republican candidates.

Ivanka’s campaign contributions have a more bipartisan bent. Records show she has donated over $240,000 to both Democrats and Republicans. Ivanka has given money to Schumer, Sen. Cory Booker, D-N.J.,, Sen. Kirsten Gillibrand, D-N.Y., Rep. Donald Norcross, D-N.J., District of Columbia Delegate Eleanor Holmes Norton, and Hillary Clinton’s 2008 presidential bid. On the Republican side, Ivanka has given money to the presidential campaigns of Mitt Romney and Sen. John McCain, R-Ariz. In 2010, Ivanka gave $2,000 to Carly Fiorina’s U.S. Senate campaign. Fiorina ran against Donald Trump in this year’s Republican primary and the pair had several contentious exchanges. Fiorina ended her presidential bid in February and endorsed another Trump rival, Sen. Ted Cruz last month. In addition to giving money to both Republican and Democratic candidates, Ivanka has donated to committees benefiting both parties.

Neither Ivanka and Eric Trump responded to requests for comment from Yahoo News. The Trump campaign also did not respond to a request for comment. Along with Donald Jr., Ivanka and Eric, Trump has two younger children. Tiffany Trump, 22, has not been as active in the campaign as her older siblings and Yahoo News could not find voting records for her. Trump’s youngest son, Barron, is just 10 years old.

New York State Board of Elections records show that both Trump and his wife, Melania, are members of the Republican Party. But Trump has a rather unusual relationship with the Republican Party, and has sometimes been at odds with the Republican National Committee. Like his daughter, Trump has given money to members of both parties.
