(CNN) The Republican National Committee spent over $424,000 at Trump properties in the first two months of 2018, according to Federal Election Commission documents.

In just February, according to FEC documents made public Tuesday, the RNC spent more than $271,000 on venue rental and catering at Trump properties in Florida and Washington, DC.

FEC filings also show that starting in September 2017, the RNC has paid $37,000 monthly to rent space in Trump Tower for the Trump campaign, totaling over $225,000 so far.

The $271,000 is about 86% of the committee's entire spending on venue rental and catering for the month, and more than the committee has spent in a single month at a Trump property since the beginning of 2017. Overall, 14% of RNC spending on venue rental and catering has gone to Trump properties since the beginning of 2017.
