The Democratic National Committee raised only $4.29 million in May, the organization's worst fundraising performance in that month since 2003, according to data from the Federal Election Commission.

In May 2003, the DNC raised $2.7 million, but since that time, the party's worst totals in May had previously been $4.5 million in both 2005 and 2015. It is common for fundraising totals to dip in the year following a presidential election race.

This comes one month after the DNC posted its worst April in terms of fundraising since 2009, hauling in just $4.7 million. That meant the Democrats' fundraising total dipped more than $400,000 from April to May.

MSNBC host Hallie Jackson pressed new DNC chair Tom Perez on the poor April total last week, but he said he only "got there on March 1."

"I was the first to say, we have a lot of rebuilding to do," he said.

The Democrats' 2016 presidential nominee, Hillary Clinton, criticized the DNC last month as "on the verge of insolvency" and for having an outdated data operation waiting for her when she won the nomination.
