GOP frontrunner Donald Trump is opening his campaign headquarters in Sacramento, California next week ahead of the state’s primary on June 7.

The Sacramento Bee reports the office will be in the Natomas area. Sacramento, the California state capital, is the place where state legislators and lobbyists conduct business daily.

Trump’s California state director Tim Clark says the office will be open and in operation next week, as well as another space located in Southern California.

Clark, who took recently the job as Trump’s California state director, is organizing volunteers across the large state where Trump plans to hold several campaign visits over the next several weeks.

Trump is scheduled to speak at the California GOP convention on April 29.
