The National Governors Association is pulling out of an annual meeting at the White House after Donald Trump declined to invite two Democratic governors, undercutting one of Washington’s few remaining bipartisan gatherings.

Trump is still expected to meet with governors at the White House on Friday but the event will not be facilitated by an organization founded more than a century ago to help state leaders from both parties advocate for their interests in Washington. The Republican president had refused to include Democratic Govs. Jared Polis of Colorado and Wes Moore of Maryland and recently blasted them on social media as “not worthy of being there.”

In a brief interview Thursday, Polis said he does not have “any ability to get in (Trump’s) head.” Polis said he was nonetheless meeting with governors from both parties while he is in the nation’s capital.
