WASHINGTON (Reuters) - Democratic presidential candidate Beto O’Rourke raised $3.6 million in the second quarter, according to his campaign, a lackluster haul for a candidate once considered a fundraising juggernaut.

O’Rourke raised $9.4 million in his first two weeks running for president in the first quarter, but then saw his fundraising dry up as he failed to gain traction in the polls.
