New fundraising reports show U.S. Democratic presidential hopefuls Hillary Clinton and Bernie Sanders each raised more than $26 million in April, as Sanders tries to cut Clinton's lead in delegates needed to win the party's nomination.
But the reports, filed with the Federal Election Commission, show Sanders' spending has far outpaced Clinton's, leaving him with just $5.8 million on hand, compared with Clinton's reported $30 million.
Sanders' small hopes of catching Clinton depends on his winning a big victory in the California primary early next month.
The data show the pace of Sanders' fundraising slowing considerably from the more than $40 million he raised in February and again in March.
The reports also indicate that groups supporting the presumptive Republican nominee, Donald Trump, have just begun to step up fundraising efforts.
The political action committee Great America, which is seeking funding from wealthy Trump supporters, reported raising just over $1 million through the end of April.
The New York Times reported Saturday that more than a dozen of the Republican Party's most reliable big donors have indicated they will not contribute to or raise money for Trump, who has split the party and alienated an array of high-profile establishment Republicans.
New York investor Paul Singer, who has spent at least $28 million for national Republicans since 2012, has disavowed the Trump candidacy.
The report quotes another financier, hedge fund manager William Oberndorff, as saying "if it's Trump vs. Clinton, I will be voting for Hillary."
