Highlights: The Trump presidency on Feb. 10 at 8:40 A.M. EST

IMMIGRATION

The Trump administration is pressing ahead on multiple legal fronts after suffering a setback by a U.S. appeal court that refused to reinstate his temporary travel ban on refugees and citizens from seven mainly Muslim countries.

Trump’s proposed barrier along the U.S.-Mexico border would be a series of fences and walls that would cost as much as $21.6 billion and take more than three years to construct, according to a report seen by Reuters.

JAPAN

With differences simmering in the background, Trump and Japanese Prime Minister Shinzo Abe open two days of talks looking to build a close relationship.

CHINA

Trump changes tack and agrees to honor the "one China" policy during a phone call with Chinese leader Xi Jinping, a major diplomatic boost for Beijing, which brooks no criticism of its claim to self-ruled Taiwan.

RUSSIA

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.

AFGHANISTAN

The Afghan Defense Ministry is welcoming suggestions by the U.S. commander of international forces in Afghanistan that more troops are needed to train the security forces trying to hold back a growing Taliban-led insurgency.

IRAN

Hundreds of thousands of Iranians rally to swear allegiance to the clerical establishment following Trump's warning that he had put the Islamic Republic "on notice," state TV says.

Trump's bellicose rhetoric toward Iran now appears likely to help keep President Hassan Rouhani in office for another term but will make it harder for the Iranian leader's team of moderates to govern.
