Washington, Jun 2 (IANS): Democrat front-runner Hillary Clinton raised over $40 million in overall contributions in May, an increase of more than $5 million from her April fundraising figures, campaign officials said.

Of that sum, $27 million went to her campaign (Hillary for America), while the remaining $13.5 million went to the Democratic National Committee and states parties, Politico reported.

According to the campaign, Hillary for America now has $42 million as the former secretary of state enters the final stretch of the primary season -- June 7 will be the last big day, with voting in California, New Jersey, New Mexico, Montana, South and North Dakota.

"Thanks to the continued support of more than 1.3 million people across the country, we have the resources we need to run a winning general election campaign and build on the smart investments we made during the primary," Campaign Manager Robby Mook said on Wednesday.

"Hillary Clinton remains focused on ensuring that she and Democrats up and down the ballot are able to mobilize millions of voters and win in November," he said.

In April, Clinton’s campaign directly received $25.1 million, compared with $26.9 million raised by Sanders, according to reports filed with the Federal Election Commission.

Her campaign also raised an additional $9.5 million for various Democratic Party committees.
