JOHN YANG: In tonight's other headlines, the Senate has begun debating President Trump's tax and spending bill that Republicans hope to get to the oval office by July 4th.

The Senate narrowly agreed late last night to take up the measure, but the Democrats forced Senate clerks to read the entire 940 page bill out loud, a process that took more than 15 hours.

The nonpartisan Congressional Budget Office says the Senate version of the bill would add more than $3 trillion to the national debt over 10 years.

And Senator Thom Tillis of North Carolina, one of two Republicans to vote against advancing the bill last night, said he won't run for reelection.

Tillis said the bill's Medicaid provisions would be devastating to his state.
