And it comes as Americans are increasingly down on Trump's handling of the war the U.S. started with Iran.

They have been quietly reviewing documents for months, sometimes late into the night, sources say.

Amid concerns over the possibility of mines in the Strait of Hormuz, robots are offering a safer option to assess risks in the water.

The attacks come as U.S. and Iranian officials have been negotiating about maritime traffic in the Strait of Hormuz, a key waterway through which some 20% of the world’s oil passed before the war.

Defense officials asked for more than $67 billion in supplemental funding. But Congress hasn’t approved the money yet, in part because of frustrations over information about the war with Iran, sources say.

The U.S. military launched new attacks on Iran Tuesday in retaliation for Iranian attacks against commercial ships in the Strait of Hormuz, U.S.

The renewed clashes came as President Donald Trump was in Turkey for a NATO summit and while Iran was holding a massive dayslong funeral for its slain Supreme Leader Ayatollah Ali Khamenei.

Trump later switched planes at an air base in England, where he said he let service members tour the new Air Force One.

The president is receiving an array of advice on next steps in Iran, with supporters of a return to war seizing on recent tensions to make their case.

The Pentagon has said the war has cost the U.S. about $30 billion, but an internal overall cost estimate is $80 billion to $100 billion, sources say.
