California Democrats are clashing with other members of their party over a package of antitrust bills targeting the top tech companies in the country.

Democratic lawmakers from California on the House Judiciary Committee, particularly those representing tech-heavy Bay Area districts, voted against the majority of their colleagues over the past two days on five antitrust bills that seek to rein in the market power of Amazon, Apple, Facebook and Google.

The stiff opposition from the California delegation may cause further hurdles as the legislation heads to the House floor, with moderate and progressive Democrats, as well as prominent Republicans, voicing concern over the bills.

Democratic Reps. Zoe LofgrenEric Swalwell and Lou Correa — all from California — voted against advancing nearly every bill the committee marked up Wednesday and Thursday.
