Republican presidential nominee frontrunner Donald Trump will make an appearance in the Bay Area as a speaker at the California Republican Party Convention on Friday.

According to officials, Trump will kick off the convention with a keynote speech at the lunch banquet. Republican candidates Ohio Gov. John Kasich and Texas Sen. Ted Cruz will also make guest appearances on Saturday and Sunday.

The convention will be held at the Hyatt Regency San Francisco Airport in Burlingame Friday through Sunday.

The event is open to the public and requires a registration fee. It will feature various workshops that will address local government campaigns, grassroots movements and national security matters, to name a few, according to the convention schedule.

Several groups in the Bay Area are organizing peaceful protests geared specifically toward Trump’s appearance in the Bay and will take place outside of the convention. One particular group that mobilized on Facebook has attracted 8,500 interested people, 2,400 of whom have said they will attend.

The candidates’ visit comes on the wings of Tuesday’s primary elections in Connecticut, Delaware, Maryland, Pennsylvania and Rhode Island. Trump led the votes in each state by at least 30 percent over his opponents, according to the April primary results. Results list Trump with a total of 949 delegates, Cruz with 544 and Kasich trailing with 153. The number of delegates needed to secure the Republican nomination is 1,237.

There are only 10 states left that have yet to hold primaries, the next being Indiana on May 3, according to the GOP.

The California primaries will take place on June 7.
