Amid a heavy barrage of advertising by opposing "super" political groups, President Barack Obama's re-election campaign spent more than it collected in June.
While outraised again by Republican Mitt Romney, Obama ended the month with a hefty $97.5 million in the bank.
Finance reports filed Friday show June as the second consecutive month in which Romney brought in more money than Obama.
Obama tried to answer the super PACs supporting Romney by spending $38.2 million on television advertising. Romney spent less than a third of that - $10.4 million - on TV time.
Romney's campaign nearly doubled its spending in June compared with the previous month.
Romney raised $106 million with the help of the GOP. Much of that came from larger donations in a handful of battleground states.
