Buck pointed out that Ryan followed up with his own budget blueprint and subsequently worked with Sen. Ron Wyden (D-Ore.) on a bipartisan health care plan.
"It's hard to criticize Paul Ryan for not addressing deficits," he said.
Ryan also failed to mention that House Republicans repeatedly walked away from debt talks with the president - not the other way around.
Obama and his administration engaged in months of talks with Speaker John Boehner (R-Ohio) and House Majority Leader Eric Cantor (R-Va.) last year - and each time, the GOP walked away from the table, refusing to accept a tax increase on the wealthy alongside trims in entitlements and other spending.
Obama did, however, sign a $2.1 trillion deficit-cutting package last year in the end, with no tax hikes attached, and he proposed his own $4 trillion plan last September.
Ryan also repeatedly blasted Obama for cutting $716 billion from Medicare without noting that his own budgets, the ones that made his name as a bold budget-cutter, had even greater Medicare cuts before much steeper trims would take effect in 2022. Romney has rejected those cuts but embraced Ryan's larger remaking of the program for future retirees.
"Ryan, who wants to turn Medicare into a voucher program and tried to raid it to pay for tax cuts for wealthy, masquerades as its protector," Axelrod tweeted.
Buck said Ryan didn't cut Medicare to pay for a new entitlement program like Obama did, and he noted that Romney has vowed to reverse the cuts.
"Paul Ryan joined the Romney ticket, not the other way around, and Romney is going to restore those cuts," Buck said.
