Attorney Ro Khanna, a Democrat seeking to defeat longtime Rep. Michael M. Honda, D-Calif., has started to air his second advertisement of the race — a sign the challenger is becoming more aggressive ahead of a June primary.  

In the 30-second ad, released on Monday, Khanna broadly describes a few of his policy proposals if elected to Congress. For example, he suggests adding computer coding to the curriculum in public schools – an issue that could resonate in the Silicon Valley-based 17th District.

Khanna, Honda, Republican physician Vanila Singh and a handful of other lower-tier candidates will face off in a “jungle” primary on June 3. The top two vote recipients, regardless of party, will advance to the general election in November.  

Khanna’s campaign did not immediately return a request for information on where and when the ad will air. Khanna’s campaign will report nearly $2 million in the bank as of March 31, giving him ample funds for advertising.  

Khanna’s campaign is backed by a number of Silicon Valley leaders , including Google Chairman Eric Schmidt, Yahoo CEO Marissa Mayer and Facebook Chief Operating Officer Sheryl Sandberg, among others.  

Honda’s campaign, on the other hand, is backed by the vast majority of the California delegation , as well as President Barack Obama .  

California’s 17th District is rated a Safe Democrat  contest by Rothenberg Political Report/Roll Call.
