HuffPo:
After bragging for a year about how cheaply he was running his campaign, Donald Trump is spending more freely now that other people are contributing ― particularly when the beneficiary is himself.

Trump nearly quintupled the monthly rent his presidential campaign pays for its headquarters at Trump Tower to $169,758 in July, when he was raising funds from donors, compared with March, when he was self-funding his campaign, according to a Huffington Post review of Federal Election Commission filings. The rent jumped even though he was paying fewer staff in July than he did in March.
The campaign is a profit center!
