--ANALYSIS: TRUMP'S TWITTER USE BRINGS RISKS AND REWARDS: It’s no secret that President Donald Trump does things his own way. During the campaign through 99 days of his presidency, the 45th president likes to keep everyone on their toes and that’s in no small part to his tweeting habits. Through his tweets to his over 28 million followers on his @realDonaldTrump account, the country gets a real-time window into his thinking. The president is publicizing, urging action, throwing out red meat to supporters, letting everyone in on his TV habits and often just venting, but the country gets to follow along.

GOP PUSHES FOR A 1-WEEK FUNDING BILL TO AVERT GOVERNMENT SHUTDOWN. To avert a government shutdown at the end of the week, lawmakers are hoping that a stopgap measure will provide congressional leadership more time to negotiate a larger funding bill. The deadline for Congress to pass a spending bill is midnight Friday, but a short-term continuing resolution, or CR, introduced late Wednesday by House Appropriations Committee Chairman Rodney Frelinghuysen, R-N.J., would extend funding to May 5, until Congress can pass a bill that would fund the government through September, explains ABC's VERONICA STRACQUALURSI. http://abcn.ws/2pqSwua
