Cash kept flowing for Hillary Clinton in April.

The former secretary of state's campaign committee reported total receipts of about $25 million for the month and ended it with more than $30 million on hand, according to federal data filed Friday. While her Democratic rival Sen. Bernie Sanders outraised her with about $27 million in receipts, his campaign also spent more and ended April with $5.8 million on hand.

Clinton had one clear money advantage over Sanders and presumptive Republican nominee Donald Trump . A pro-Clinton Super PAC raked in large sums from some big-name families as it gears up for a likely general election slugfest with Trump.

Priorities USA Action, which cannot coordinate with the Clinton campaign but can spend in support of her, reported receipts of $8.6 million in April. It closed the month with more than $46 million on hand, and plans to spend money on negative ads against Trump, among other efforts.

Here are some of the donors who gave to the committee in April:

Sanders, who has only a slim chance of securing the nomination, has repeatedly bashed the political influence of large donors and fueled his campaign mostly on small individual contributions. Campaign finance reform is a key part of his platform.

Trump's campaign, meanwhile, took in only about $14 million in contributions through April. Trump himself has loaned more than $43 million to the campaign, though it can reimburse him if it receives enough contributions.

Trump appealed to many GOP primary voters by saying that since he self-funded his campaign, special interests cannot influence him. However, as his campaign this month turned toward the general election, it started to set up a fundraising organization and signed a joint fundraising agreement with the Republican Party.
