(AP) - Connecticut Gov. Ned Lamont has changed the state's presidential primary from April 28 to June 2, as part of an effort to help stop the spread of the coronavirus.

Connecticut on Thursday became the latest state to change its primary date. The move makes it mathematically impossible for Joe Biden to clinch the nomination before May.

The other states to postpone are Maryland, Georgia, Kentucky, Louisiana and Ohio.
