Pennsylvania became the latest state to postpone primary elections, moving the state’s presidential and congressional primaries from April 28 to June 2.

Democratic Gov. Tom Wolf made the move official Friday, signing a bill moving the primary date into law. The measure passed the state legislature on Thursday.

“Delaying this year’s primary election as several other states have done is in the best interests of voters, poll workers and county election officials,” Wolf said in a statement.

“I commend the General Assembly for acting quickly on this critical legislation. The Department of State will continue to work with local election officials to ensure Pennsylvania has a fair and accessible election.”

Pennsylvania, which President Donald Trump narrowly won in 2016, will be a key state in the presidential race. It’s also the home of former Vice President Joe Biden’s campaign headquarters.

Pennsylvania will also have competitive House races, and the delayed primary means the general election matchups won’t be known until June. Republicans and Democrats are each defending two competitive House seats in 2020.

Pennsylvania is the 14th state to postpone elections amid the crisis.
