Washington (CNN) - A nagging head cold hasn't kept Mitt Romney from working feverishly to fill his campaign's coffers this week.
After giving an education policy speech in Washington, the presumptive GOP nominee will continue this week's punishing fund-raising schedule with a small finance event in the nation's capital, a campaign aide said.

Thanks to more than eight fund-raisers this weekend, Romney hauled in about $15 million during a swing through New York and Connecticut, the campaign finance chair told supporters Tuesday.
Federal disclosure reports show Romney has begun to close the gap between his fund-raising operation and that of President Barack Obama.
The former Massachusetts governor told reporters Wednesday that a cold had not slowed him down.
Asked if he used any special remedies to shake off the sniffles, Romney laughed: "Rest, which I didn't employ."
Romney will also spend time Wednesday afternoon attending some private meetings.
