Good Tuesday morning. Here are some of the stories making news in Washington and politics today.

• After withdrawing the United States from the international Paris climate change accord and seeking to roll back or weaken over 80 environmental regulations, President Trump delivered a speech Monday calling himself a defender of the environment. One climate expert called his claims “a true ’1984’ moment.”

• Mr. Trump lashed out at Britain’s ambassador to the United States, saying the White House would no longer deal with him after the publication of confidential cables in which the ambassador disparaged the Trump administration as “clumsy and inept.”

• A few changes to the Democratic primary: Representative Eric Swalwell has dropped out of the race, and Tom Steyer, the California billionaire spearheading an effort to impeach Mr. Trump, intends to enter the 2020 contest.
