Good Wednesday morning. Here are some of the stories making news in Washington and politics today.
• The Supreme Court’s conservative majority seems poised to allow the Trump administration to add a question on citizenship to the 2020 census. Adding the question, government experts said, could depress participation in the census (about 6.5 million people might not be counted) and affect how congressional seats are allocated. (Here’s a look at how it could alter the maps.)
• Robert Mueller’s report stopped short of declaring whether acts by President Trump were illegal attempts to impede the investigation. But his report is a detailed map to the answers.
• Is obstruction an impeachable offense? Mr. Trump tweets no. History says yes. Impeachment proceedings against Presidents Richard Nixon and Bill Clinton could provide a guide to House Democrats.
• Stephen Moore, the economic adviser Mr. Trump plans to nominate to the Federal Reserve, wrote in 2000 that “radical feminists” had turned white men into an “oppressed minority” on college campuses, raising new questions about the president’s pick.
• Setting up what was expected to be an extended legal clash between two branches of government, a White House official said that Mr. Trump would not comply with a Tuesday deadline set by House Democrats to release his tax returns to Congress.
• William F. Weld, the only Republican challenging Mr. Trump so far, is betting that there are still enough Republicans and independents who find the president so objectionable that they can be moved to do what voters rarely do: defeat the sitting president in a primary.
• Joe Biden, who is officially entering the race on Thursday, is ahead in some polls but behind financially. He’s seeking out top money bundlers to catch up in the money race, but that risks a backlash among grass-roots Democrats.
• Two months into his second presidential bid, Senator Bernie Sanders is atop the field of announced Democratic candidates. Mr. Biden’s expected entry could change that. Mr. Sanders is not likely to care.
• A year after Florida legislators passed a surprising bipartisan gun bill in the wake of the Parkland shooting, the State Senate on Tuesday voted to expand a program that allows teachers to carry guns to school.
• M.J. Hegar, a former Air Force helicopter pilot who narrowly lost a bid for the House in November, will challenge Senator John Cornyn, a fixture in Texas Republican politics, in 2020.
