Inside Trump's week of European visits

• Macron has also worked behind the scenes to try to persuade Trump to re-engage with the international community on climate change after he dramatically announced the United States' withdrawal last year from the Paris climate accord.
• Sources who've worked closely with Trump are skeptical about whether Macron's assiduous and successful efforts to build personal chemistry with Trump will pay off and sway Trump on either Iran or climate change.

Behind the scenes: Trump's ambassador-to-Germany-in-waiting, Ric Grenell, was seen at Mar-a-Lago on Saturday night talking to Trump. Grenell, who was there for dinner, was being introduced around the room by Terry Allen Kramer, a long-term Palm Beach resident and Broadway producer, and by the president's friend Chris Ruddy.

• According to a source who saw the president make the rounds of the room at Mar-a-Lago, Trump spent a substantial amount of time talking to Grenell.

• The president has let it be known he's impatient with the hold-up in the Senate over Grenell's confirmation and has told people he had wanted to get it done before Merkel's visit this week.
