Today's Headlines: Health Care, Debates, Protests and Sessions

This and more in today's headlines:

Senate Republicans narrowly pushed through a procedural vote to open debate on plans to repeal and maybe replace the Affordable Care Act Tuesday — but then suffered a defeat only hours later when Republicans failed to muster enough votes to pass their replacement bill.

First, on Tuesday, the Senate voted 50 to 50 to open the debate, with Vice President Mike Pence then breaking the tie. Two Republican senators, both women—Susan Collins of Maine and Lisa Murkowski of Alaska—joined Democrats in voting against the motion to proceed. Arizona Senator John McCain returned to Capitol Hill to cast a decisive vote to open debate, only a week after being diagnosed with brain cancer.

Nearly 100 people were arrested throughout the day as the Senate opened debate on the Republicans’ plans to repeal and maybe replace Obamacare.

Also, President Trump is continuing to publicly humiliate his own attorney general, Jeff Sessions, telling reporters Tuesday he thinks it’s unfair Sessions recused himself from the investigation into alleged Russian meddling in the 2016 election.
