(CNN) Republican campaigns, committees and outside groups have spent more than $1.7 million at Trump properties through the first six months of 2018, with over half of that spending coming from the Republican National Committee, according to a CNN analysis of FEC filings.

In addition to the RNC -- which spent a little more than $990,000 at Trump properties through the end of June -- the Trump 2020 re-election campaign and American First Policies, a leading super PAC supporting the President, have both spent around $200,000. The Great American Committee, another pro-Trump outside group, spent $116,000 at the properties.

Other groups that spent between $10,000 and $100,000 include the National Republican Senatorial Committee; Cotton Victory (a joint fundraising committee helmed by Sen. Tom Cotton); the campaign committee of Greg Pence, Vice President Mike Pence's brother; and the Senate Leadership Fund (a leading Republican super PAC) and Protect the House (another conservative outside PAC).

Trump properties raking in campaign cash include Mar-A-Lago in West Palm Beach, Trump National Doral in Miami, the Trump International Hotel in Washington, DC, and Trump Tower in New York, which combined brought in more than 96% of the $1.7 million. A slew of other Trump-owned or branded locations received just under $60,000.

The largest spending went to venue and rental catering at the Trump International Hotel in DC and Trump National Doral -- which received more than $367,000, likely related to hosting the committee's 2018 summer meeting. America First Action spent nearly $60,000 on an event at the Trump International Hotel in DC.
