Donald Trump's campaign said Thursday that it raised a record $3.5 million in a single day through online fundraising.

While the campaign did not specify the precise day in its announcement, it noted that the "record haul came as America was introduced to Governor Mike Pence as Mr. Trump's running mate." Trump announced Pence as his vice presidential pick on Friday and held an event in Manhattan on Saturday. The Indiana governor formally accepted his party's nomination on Wednesday night.


"Governor Pence has ignited the passion of grassroots conservatives with his record of creating jobs, and enacting conservative reforms which have turned Indiana into a model for the rest of the country," the campaign said.

The campaign's announcement, which comes hours before Trump officially accepts the Republican presidential nomination, also said that more than 750,000 individual donors have contributed since the campaign launched its online fundraising operation last month.
