• The ego's a fragile thing. A new analysis on the gender of corporate board directors by executive search firm Egon Zehnder found that, while the U.S. initially lead the charge in diversifying corporate America, it has fallen behind much of the developed world over the past four years. In 2012, women accounted for 19% of board seats on U.S. companies, while women in Western Europe held about 15.6% of seats. Four years later, the U.S. has seen incremental progress—women now make up about 20% of directors—while that percentage has jumped to 25.6% in Western Europe.

One potential reason for corporate America's lack of progress? Ego, says Carol SingletonSlade, who leads Egon Zehnder's U.S. boards practice. She points out that there's "a cultural mindset in the U.S. that if you exit a board, it's a sign of failure" and that for that reason, "There's a lot of ego tied up in tenure on boards." Indeed, the average U.S. board member is older and has a longer tenure than those of most other developed countries, and in a quarter of major companies, directors serve  for a decade or longer. This helps explain why board seats in the U.S. are so hard to come by—and why gender ratios have been so slow to change. Fortune

• Warren won't be silenced. Sen. Elizabeth Warren (D-MA), was formally silenced by her Republican colleagues during a Tuesday night debate on President Trump's nominee for attorney general, Sen. Jeff Sessions (R-AL). Her offense? "Impugning the motives" of the Alabama Senator by reading a letter from Coretta Scott King that dated to his failed judicial nomination 30 years ago. King wrote that when acting as a federal prosecutor, Sessions used his power to "chill the free exercise of the vote by black citizens." Warren read the letter anyway, right outside of the Senate floor. Sessions' confirmation is expected today. Time
