Tuesday roundup: Dingell to retire, PBS vs. NPR in March Madness, #SheDocs returns

• U.S. Rep. John Dingell, who helped sign the 1967 Public Broadcasting Act into law and remained a staunch supporter of pubcasting, is retiring after a record 58 years in Congress. “I find serving in the House to be obnoxious," the 88-year-old Michigan Democrat said at a Monday luncheon. "It’s become very hard because of the acrimony and bitterness, both in Congress and in the streets.”

• March Madness is approaching quickly, but this bracket competition has nothing to do with basketball. WHYY in Philadelphia is sponsoring PBS vs. NPR: Public Media Madness, which encourages pubmedia fans to vote for their favorite TV and radio personalities.
