(CNN) - Hillary Clinton hit Texas and Ohio airwaves Monday with two new television spots, including one that goes after Barack Obama for not holding any oversight hearings since becoming chairman of a Senate Foreign Relations subcommittee.
"Barack Obama says he has the judgment to be president, but as chairman of an oversight committee charged with the force of fighting al Qaeda in Afghanistan, he was too busy running for president to hold even one hearing," an announcer says in a 30-second Texas ad called "True."
"Hillary Clinton will never be too busy to defend our national security, bringing our troops home from Iraq and pursuing Al Qaeda in Afghanistan," the announcer also says.
Clinton first criticized Obama over his chairmanship of a subcommittee on Europe at last week's MSNBC debate.
'"It has jurisdiction over NATO. NATO is critical to our mission in Afghanistan," she said then. "He's held not one substantive hearing to do oversight, to figure out what we can do to actually have a stronger presence with NATO in Afghanistan."
Obama responded that he became chairman of that committee in January 2007, just as his presidential campaign was launching.
Clinton also went up with a new 30-second ad in Ohio on Monday called "Partner," in which she highlights the state's economic downturn and says she will fight for working families.
"The wealthy and the well-connected have had a president. It's time the middle class had a president who will stand up for you," Clinton says in that ad.
