NEW YORK - Campaign finance reports show presumptive Republican nominee Donald Trump took in just over $5.5 million last month, about a fifth as much as Hillary Clinton's $26 million.

The Trump campaign started this month with $1.3 million in the bank, less than many candidates for Congress. As donors withheld dollars, Hillary Clinton questioned his sense in a speech on Tuesday.

Trump hit back in an interview with CBS News' Norah O'Donnell.

"She will do horribly on the economy. You look at what she did as Secretary of State. What China did to this country it was pillage. They pillaged this country," Trump said.

Asked how he can run a campaign without adequate fundraising, Trump said he's not concerned with raising money.

"I don't want to devote the rest of my life to raising money from people," he told O'Donnell. "All of the money [Clinton] is raising is blood money."
