Republican Donald Trump and the Republican Party saw fundraising surge to $80 million last month, his campaign announced Wednesday.

Trump and the party collected $64 million through digital and direct-mail solicitations in July, and another $16 million poured in through 20 fundraising events Trump and the Republican National Committee hosted, campaign officials said in a news release.

The real-estate magnate also donated another $2 million to his campaign in July, bringing his total investment in his White House bid to more than $56 million, his aides said.

Trump aides say the campaign and the party committees began August with combined $74 million in cash reserves.

The July haul marks the strongest fundraising month for Trump and the GOP of the election cycle and comes as the Republican presidential nominee faces a barrage of criticism over his repeated attacks on the parents of a slain Muslim-American soldier, his comments about workplace sexual harassment and his refusal to endorse several prominent Republicans who face primaries this month.

Trump is racing to to catch up to his Democratic rival Hillary Clinton. This week, Clinton announced that she has raised nearly $90 million in July with the Democratic National Committee. Roughly $63 million went directly to Clinton's campaign and about $26 million went to the DNC and state parties.

Trump's campaign has not detailed how much of his fundraising total went to his campaign and how much has been funneled to the Republican Party.

Trump finance chairman Steven Mnuchin said the campaign has seen 69% growth in small-dollar donations and has the backing of more than 1 million donors.

“Our volunteers and contributors are clearly committed to electing Donald J. Trump as President in November," he said in a statement.

Full details on the candidates' fundraising and spending won't be disclosed to federal election regulators until Aug. 20. Earlier this week, Trump told a crowd in Columbus, Ohio, that he had raised $35.8 million in July but said checks still were being tallied.
