WASHINGTON (CNN) -- Sen. Hillary Clinton, D-New York, raised $26 million in contributions during the first three months of the year, her presidential campaign announced Sunday in a conference call.

Clinton transferred an additional $10 million from her 2006 Senate re-election campaign for a grand total of $36 million raised for the quarter. It is the highest amount a Democrat has raised in a single quarter in the year before the election, according to Federal Election Commission records.

Of the $26 million in contributions, approximately $4.2 million was donated via the Internet.

Clinton, along with several other 2008 presidential hopefuls, has been raising funds for both the primary and the general election, though her campaign did know how much of the $26 million would be set aside for the general.

The campaign also said it would not know how much cash it had available until later this month, when they submit their official tallies to the FEC.
