(Reuters) - Highlights of the day for U.S. President Donald Trump’s administration on Friday: Trump and Japanese Prime Minister Shinzo Abe open a new chapter in U.S.-Japan relations with Trump abruptly setting aside campaign pledges to force Tokyo to pay more for U.S. defense aid. Trump says he is considering issuing a new travel ban executive order, while White House Chief of Staff Reince Priebus says the administration could still escalate a legal dispute over Trump’s original travel ban order to the U.S. Supreme Court.  Several Democratic U.S. senators and a Republican congressman whose district includes a section of the U.S.-Mexico border express skepticism about Trump’s proposed wall there after learning the project’s estimated cost is $21.6 billion. Trump changes tack and agrees to honor the “One China” policy during a phone call with Chinese leader Xi Jinping in a major diplomatic boost for Beijing, which brooks no criticism of its claim to self-ruled Taiwan. RUSSIA-UKRAINE The Washington Post reports White House national security adviser Michael Flynn privately discussed U.S. sanctions against Russia with Moscow’s ambassador during the month before Trump took office. Flynn had previously denied discussing sanctions. Russian President Vladimir Putin proposes Slovenia, the birthplace of Trump’s wife, Melania, as a good place for a meeting with Trump, but says the decision on a location is not Moscow’s alone. Trump expresses support for an undivided Ukraine in a letter to Lithuania’s president, using language similar to that of his predecessor Barack Obama, and seen as likely to be welcomed by Kiev and North Atlantic Treaty Organization allies. Trump says Iran President Hassan Rouhani “better be careful” after Rouhani was quoted as saying that anyone who speaks to Iranians with threats would regret it. Trump pulls Elliott Abrams as a contender for the No. 2 position at the State Department after learning that the Republican foreign policy veteran criticized him during the 2016 election campaign, sources say. Tom Price is sworn in as U.S. secretary of health, which Trump says will allow his administration to fulfill his pledge to dismantle Obamacare and reshape the healthcare system. The Federal Reserve Board’s top bank regulator says he will resign, giving a boost to Trump’s plans to ease reforms put in place after the 2007-09 financial crisis.
