Trump campaign spending doubles - but he still trails Clinton
Donald Trump doubled his campaign expenses last month, yet was still spending at a far slower rate than Hillary Clinton.
New finance documents show the Republican presidential nominee's campaign spent about $18.5m (€16.3m) in July.
By comparison, the Democratic presidential nominee spent about $38m (€33.5m).
The New York businessman gave his campaign another $2m in recent weeks. He had pledged to contribute as part of a fundraising pitch to small donors, telling them he would match their efforts up to that amount. In all, his campaign brought in $37m for the month. Clinton's campaign raised $52m.
Mr Trump has continued to increase the size of his operation, putting $5m this week into his first batch of TV ads.
Ms Clinton has been running general election adverts for months.
Last month, Mr Trump brought in some new consultants and firms, according to July reports to the Federal Election Commission.
At the end of July, the campaign paid $100,000 to Cambridge Analytica, a data firm that did business with Republican opponent Ted Cruz.
Hedge fund billionaire Robert Mercer, who contributed $2m to a pro-Trump super political action committee in July, is an investor in Cambridge.
The Trump filings also show some old ties.
Two weeks after campaign manager Corey Lewandowski was ousted, the Trump campaign sent his company, Green Monster Consulting, another cheque, for $20,000.
That is about the same amount it had paid him each month while he was running the campaign.
Mr Lewandowski was already on the payroll of CNN, where he is a political contributor.
