 Now, a few minutes ago, we heard about the U.S. President Joe Biden hosting NATO leaders in Washington. There's been a huge focus on the president in the last few days, as calls for him to stand down as a Democratic candidate in November's presidential race grow. The latest comes from the movie star and, crucially, Democratic Party donor George Clooney. He says the Democrats can't win if Mr. Biden is the candidate. Well, earlier I spoke to pollster and author John Zogby.
