The runners-up for the White House in 2016 are going to battle once again on national television this week.

U.S. Sens Ted Cruz and Bernie Sanders are once again taking to CNN to do a live national debate, but this time they will have reinforcements. On Tuesday, Sen. Tim Scott, a South Carolina Republican, and Sen. Maria Cantwell, a Washington state Democrat, will join Cruz and Sanders for another debate on tax reform, this time aimed more specifically at the Republican tax cut plans being debated now in Congress.

In October, Cruz and Sanders also debated tax cuts during a CNN debate, but that was when the Trump Administration had just outlined broad plans without many specifics that have emerged since then. In that debate, Cruz stressed that Republicans in Congress must pass tax reform to live up to the campaign promises for the last few years.

"We have Republican majorities in Congress," Cruz said during the debate. "We have got to deliver on our promise to cut taxes."

Cruz and Sanders also went at it in another debate on CNN over health care earlier this year that was a big ratings hit for CNN.

The string of debates have given Cruz and Sanders a national audience even after both lost their respective bids for president in 2016.

Tuesday's debate starts at 8 p.m. CST on CNN with anchor Jake Tapper and chief political correspondent Dana Bash moderating.
