Hillary Clinton and her running mate have already raised more than $57 million in August.

Sen. Tim Kaine, D-Va., has raised approximately $11 million this month from fundraisers, and the former secretary of state has reportedly brought in a massive haul of $46 million, according to CNN's estimates.

Clinton's three-day fundraising tour of California alone raised an impressive $19 million.

The Democratic nominee's California fundraisers saw her raising cash with a multitude of A-list celebrities, including Justin Timberlake, Jessica Biel, Jennifer Aniston, Earvin "Magic" Johnson, Denzel Washington and Samuel L. Jackson.

Clinton first held a $33,400 per person luncheon in Hollywood Hills. She then moved onto another $33,400 per person luncheon in Laguna Beach. Couples who paid $100,000 were admitted to a host reception with the Democratic nominee, according to the Los Angeles Daily News.

Clinton concluded her fundraising tour with another luncheon in Laguna Beach, charging $2,700 per ticket, the report added.

The $2,700 figure is the "maximum individual contribution to a presidential candidate in the general election under federal law. Guests raising $27,000 are admitted to a host reception with Clinton," the Los Angeles Daily News explained. "The $33,400 figure is the maximum amount an individual can contribute to a national party committee in a year."

The Clinton campaign has closely guarded the star-studded affairs, and has barred the press from covering them, according to CNN.

"Clinton's traveling press corps, in a break with precedent that Barack Obama followed in 2008, has not been allowed into any fundraisers on her swing through California," wrote reporter Dan Merica. "To date, Clinton has headlined over 320 fundraisers. Only five of them have been opened to her press pool."

The Clinton campaign's to-date August haul marks a sharp increase from the $18 million she raised in July, before the Virginia senator was officially added to the fundraising efforts. Clinton also raised an estimated $40 million in June.

She is not alone in her efforts to boost her campaign's coffer: Clinton has strong support from super PACs.

The chief super PAC backing Clinton's presidential campaign raised approximately $9.3 million in July, and said it began this month with more than $38 million in cash to use in advertising against GOP nominee Donald Trump. In total, Priorities has raised $110 million for Clinton's second bid for the White House, and at least $43 million of that has gone toward ad buys targeting important swing states, including Ohio, Florida and Pennsylvania.

On the other side of the aisle, the Republican National Committee has raised roughly $200 million this election cycle. Of that amount, $27.2 million was in July. The GOP now has $34.5 million cash on hand, it said.

For perspective, the RNC raised $37.7 million in July 2012 and had $88.7 million cash on hand at that point.

The Clinton campaign also celebrated reaching a fundraising milestone this weekend.

Clinton finance director Dennis Cheng reportedly told Clinton staffers in Brooklyn, N.Y., last week that their team is already halfway to its goal of raising a staggering $1 billion, the Associated Press reported, citing anonymous sources.

The Democratic candidate helpd raise a total of $90 million in July, according to campaign manager Robby Mook.

Trump, for his part, helped raise approximately $80 million for himself and the Republican Party last month, according to a campaign spokesperson.

Reportedly spooked by Trump's July haul, Clinton and her running mate then tweaked their fundraising schedule that it now includes roughly 43 high-profile events in 14 states, according to the AP.
