OAKLAND, Calif. — After months of acrimony between California and the Trump administration over the state’s homelessness crisis, Gov. Gavin Newsom said on Thursday that he would send an envoy to meet with administration officials and discuss ways to address the issue together.

Mr. Newsom spoke of the meeting in an interview after announcing at a news conference that the state was mobilizing 100 camping trailers to shelter some of the state’s more than 150,000 homeless people.

“We really have an open hand, not a clenched fist on this,” Mr. Newsom said in the interview, inside one of the trailers arrayed in a parking lot near Oakland International Airport. “I hope we can professionalize our relationship.”

The governor toured the state this week to discuss the homelessness crisis, saying California would respond as urgently as it would to a major earthquake.
