Warren's "money bomb" event Thursday, which brought in a total of $1,194,098, coincided with Sen. Scott Brown's re-election campaign launch in Massachusetts, Politico reported.
"Today the message is clear: We have the grassroots momentum and enthusiasm to take the 'people's seat' back from Wall Street and other powerful interests," Warren told Politico in a statement. "I am grateful for this show of support and will keep working my heart out for the small businesses and middle-class families who deserve someone on their side in the Senate."
Although Warren outraised Brown in the fourth quarter, bringing in $5.7 million for her campaign, Brown still has a 2-1 cash-on-hand lead. The Warren campaign said the Harvard professor will be disadvantaged by Brown's millions and a flood of "Wall Street" cash from Republican outside groups, such as American Crossroads and the U.S. Chamber of Commerce.
"What we accomplish together today will show the world we have the grassroots organization and support to win this election, no matter what Scott Brown and Wall Street throw at us," Warren wrote in a message to supporters this week.
In his speech Thursday, Brown praised Warren as a "hardworking, talented, and accomplished academic" but said her "rock-throwing" language is not what voters want from Washington.
"Believe me, there are plenty of ideologues down in Washington already," Brown said. "What the nation's capital could really use right now is a little more respect, goodwill and bipartisanship."
