Good Tuesday morning. Here are some of the stories making news in Washington and politics today.

• Mayor Pete Buttigieg raised $24.8 million over the past three months. That total — likely to surpass the fund-raising figures of most of his rivals — is the latest evidence that he has gone from a long shot to a serious contender in a matter of months.

• Members of Congress, including Representative Alexandria Ocasio-Cortez, visited two border detention facilities in Texas on Monday and emerged describing living conditions unfit to hold adults and children, a jail-like atmosphere, and women ranging from grandmothers to a young pregnant woman in her 20s packed into cells.

• The sorority Alpha Kappa Alpha has a large membership and a multimillion-dollar budget. It’s a potential secret weapon in the campaign arsenal of Senator Kamala Harris, who joined while she was an undergraduate at Howard University.
