Boston Mayor Marty Walsh said May 4 is "too early” to reopen after the Massachusetts governor promised "clarity" on reopening the state on that date.

“I would have serious concerns if we start relaxing some of the measures we have taken in Boston and the Commonwealth on May 4, especially If it is done without a clear and thoughtful plan," Walsh said.

Earlier today, Massachusetts Gov. Charlie Baker said that later this week he would “create clarity” on reopening the state on May 4.

Walsh said that the city is working with the state to determine which public health benchmarks need to be met to determine reopening.

“We are building a framework for short-, medium- and long-term recovery," he said.

“We cannot afford any mistakes and we can’t wait for the coronavirus to go away to take next steps," Walsh added.
