WASHINGTON — Democratic presidential nominee Hillary Clinton and aligned Democratic Party committees pulled in donations at the staggering rate of more than $5.3 million a day this month to amass $101 million during the first 19 days of October, her campaign announced Thursday.

Clinton and the joint fundraising committees established with the Democratic National Committee still had $153 million in available cash as of Oct. 20, including $62.4 million sitting in Clinton’s campaign account.

The combined stockpile allows Clinton and the party to spend more than $7.6 million a day through Election Day.

Clinton and her allies already are plowing big sums into TV and digital ads and efforts to turn out voters in key battlegrounds for Clinton and other Democrats as the party tries to seize control of the Senate and chip away at the Republican majority in the House.

On Saturday, Clinton is slated to appear with singer and actress Jennifer Lopez at a get-out-the-vote concert and rally at a Miami amphitheater.

Clinton leading Trump in ad numbers

More than 774,000 people donated to Clinton between Oct. 1 and 19, her aides said in a news release. In all, more than 2.8 million people have contributed to the campaign.

“Thanks to the support of more than 2.8 million Americans, we are able to close out the final days of this campaign by running an unprecedented coordinated campaign to mobilize voters who will help elect Democratic candidates up and down the ballot," Clinton campaign manager Robby Mook said in a statement.

Clinton's campaign alone spent $50 million during the first 19 days of the month. Her single largest expense: advertising, as the campaign plowed $33 million into media buys and digital ads.

News of Clinton’s big haul came amid reports that her Republican rival Donald Trump would no longer participate in high-dollar fundraising events to benefit his campaign and the party. His aides said fundraising with the Republican Party continues but the New York businessman is concentrating on political events during the final stretch to Election Day.

Clinton also is pulling back on her appearances at fundraisers, but her high-powered surrogates continue to raise money on her behalf. Her running mate, Virginia Sen. Tim Kaine, attended five fundraising events on Tuesday alone.

Candidates and super PACs were filing their final pre-election fundraising reports Thursday.
