Tuesday's press briefing came on the heels of the GOP's newly announced 2013 budget proposal, which would slash personal income taxes to a 25 percent top rate and a 10 percent lower rate. It would also lower the top corporate tax rate to 25 percent and scrap the Alternative Minimum Tax.
House Budget Committee Chairman Paul Ryan (R-Wis.) unveiled his budget, titled “A Blueprint for American Renewal,” at the American Enterprise Institute on Tuesday.
Ryan went on the offensive ahead of the formal release of his plan, ripping Democrats for “scare tactics” over his Medicare proposal and saying that his plan addresses “all of the empty promises that our government is making.”
White House National Economic Council Director Gene Sperling responded to Ryan, calling the GOP budget plan "extremely disappointing."
"I think it's an extreme budget. This is a time when we do need to bring our debt and deficit down. We need to do it with a sense of shared sacrifice," said Sperling on MSNBC's "Morning Joe" Tuesday. "They're still not asking for a single penny of revenue to bring the deficit down."
Sperling went on to blast Ryan for "fundamentally" undermining Medicare "as we know it" in the budget plan.
Also Tuesday, President Obama meets with Irish Prime Minister Enda Kenny in the Oval Office, followed by a St. Patrick's Day lunch. Obama and first lady Michelle Obama will host a St. Patrick's Day reception Tuesday evening in honor of the visiting prime minister.
This isn't the first of the president's St. Patrick's Day celebrations. Obama stopped by The Dubliner, a raucous Irish pub on Capitol Hill, for a pint of Guinness on Saturday.
The president will also meet with Vice President Biden and Defense Secretary Leon Panetta in the Oval Office in a closed meeting Tuesday afternoon.
