Donald Trump’s presidential campaign has spent $0 on advertising for the third consecutive month since the primary contest concluded, meaning he is now being outspent by all three of his opponents: Hillary Clinton, Gary Johnson and Jill Stein.

Clinton, the Democratic nominee for president, has continued to funnel money into a negative ad barrage against Trump nationally and in a handful of crucial battleground states. According to the latest ad-spending totals by NBC News, the former secretary of state and her allies have spent $91 million since June.
