Sen. Elizabeth Warren (D., Mass.) said Tuesday she supported decriminalizing illegal border crossings, arguing the U.S. shouldn't be prosecuting "mamas and babies trying to flee violence."

Warren told HuffPost in a statement she agreed with the stance of fellow 2020 contender Julián Castro, the former Housing and Urban Development chief in the Obama administration. Castro pushed in April for a repeal of a law that makes crossing the border without authorization a misdemeanor punishable by up to six months in jail, with harsher sentences for repeat offenders.
