Sen. Elizabeth Warren's re-election campaign says the Massachusetts Democrat raked in more than $3.4 million in campaign contributions during the second quarter of the year.
Warren is running for a second six-year term and has frequently sparred with President Donald Trump both verbally and on social media.
Warren's fundraising total during the April-June period was lower than in the January-March period, where she reported more than $5.2 million in donations. Yet with more than $11 million in her campaign account at the close of the second quarter, Warren is likely to enjoy a formidable cash advantage over Republican challengers.
Shiva Ayyadurai, a Cambridge technology entrepreneur, is seeking the GOP nomination.
State Rep. Geoff Diehl of Whitman, who co-chaired Trump's campaign in Massachusetts, is strongly considering a run as well.
