POTUS is back in town.

As we noted yesterday, President Obama touched down Thursday evening at SFO in Air Force One and stepped off the plane alongside Palo Alto Congresswoman Anna Eshoo, and then avoided traffic on 101 by hopping onto a helicopter, Marine One, to shuttle him up to Crissy Field. As CBS 5 reports, "The helicopter landed with two osprey escorts just before 6 p.m."

He's here to attend the seventh annual Global Entrepreneurship Summit which kicks off this morning at Stanford, and apart from his dinner in SF Thursday night, this is a wholly South Bay affair, with the mayors of San Jose, Sunnyvale, and Mountain View along with Dave Cortese, president of the Santa Clara County Board of Supervisors arriving to greet the President last night, as the Chronicle reports.

Per standard procedure, Obama spent the night at the Intercontinental in SoMa — which necessitates the closures of part of Fifth Street as well as part of Howard Street, which won't reopen until 3 p.m. today. And reportedly there was a small group of protesters at the hotel protesting the Supreme Court's decision (which is not Obama's fault) which will stop the creation of a program to help eligible immigrant parents avoid deportation.

And Thursday night the President had dinner with a group of tech industry leaders at Twenty Five Lusk in SoMa, just a few blocks from his hotel.

Per the Chron, "Among the guests were John Doerr, a venture capitalist at Kleiner Perkins Caufield & Byers; LinkedIn Chairman Reid Hoffman, Claire Lee, managing director of Silicon Valley Bank; Elizabeth Gore, entrepreneur-in-residence at Dell; Stanford University President John Hennessy; Stephen Ozoigbo, CEO of the African Technology Foundation; Dave McClure, founder of 500 Startups; venture capitalist Chamath Palihapitiya; Google CEO Sundar Pichai; and Mary Grove, director of @GoogleforEntrep."

As we speak, Obama is set to speak before about 700 people at the Entrepreneurship Summit, where attendees will also be hearing from Mark Zuckerberg, Google's Sundar Pichai, AOL co-founder Steve Case and cast members of HBO’s Silicon Valley — who are obviously there as comic relief.
