President Donald Trump is heading to Rome on Friday to attend the funeral of Pope Francis on Saturday. The trip provides an opportunity for impromptu diplomacy, as dozens of other heads of state and government are slated to attend, including Ukrainian President Volodymyr Zelensky, British Prime Minister Keir Starmer and French President Emmanuel Macron. Notably expected to be absent: Russian President Vladimir Putin. Meanwhile, Trump’s approval ratings on immigration, relatively strong in the early weeks of his second term, have dipped into negative territory, according to a Washington Post-ABC News-Ipsos poll.
