A new book alleges that President Donald Trump told donors he threatened Russian President Vladimir Putin with bombing Moscow if Russia invaded Ukraine.

The Pentagon last week announced that it would hold back some weapons pledged to Ukraine because of what U.S. officials said were concerns that American stockpiles were in short supply.

Following the Pentagon announcing a pause on weapons, the U.S. president said Ukraine must defend itself from Russia.

The US president said he will send weapons to Nato, which he said would pay and then give the weapons to Ukraine.
