SEATTLE (AP) — Gov. Jay Inslee will seek the 2020 Democratic presidential nomination, mixing calls for combating climate change and highlights of his liberal record, with an aggressive critique of President Donald Trump.

The 68-year-old governor is launching his bid Friday in Seattle. He’s the first governor to join a Democratic primary that has been dominated by senators.

It won’t be easy for Inslee to garner attention with six prominent senators already running. Former Vice President Joe Biden and former Texas Rep. Beto O’Rourke also are expected to make highly anticipated 2020 announcements in the coming weeks.

Inslee acknowledges his underdog status but says his emphasis on combating climate change will set him apart.

He promises substantial investment in clean energy sources that reduce American dependence on fossil fuels.
