Good Tuesday morning. Happy holidays. Welcome to another hour of squawk on the street. I'm Sarah Eisen with Scott Wapner, live at post-9 of the New York Stock Exchange. Carl and David have the morning off.

Stocks are rallying the S&P 500s up almost a half a percent right now. Nasdaq is leading again up almost three quarters of one percent, adding to gains, month to date up three and a half percent, date up 32.5% besting the S&P's almost 26% rise.

report to the White House failing to reach a consensus on whether to reject or approve the deal

on national security grounds. President Biden has 15 days to make a final decision.

And the CFPB is going after Rocket Homes, one of the largest mortgage lenders in the U.S.,

accusing the company of an illegal kickback scheme to steer mortgage applications back to rocket.

This comes a day after the group also sued Walmart.

First up, though, let's start on the big banks.

Financials are higher. This is a story
