David Hale was summoned by the Pakistan foreign office on Monday to explain Trump's tweet, media said. A spokesperson for the U.S. Embassy in Islamabad confirmed the meeting took place.
In a withering attack, Trump on Monday said the United States had "foolishly" handed Pakistan more than $33 billion in aid in the last 15 years and had been rewarded with "nothing but lies and deceit".
"They give safe haven to the terrorists we hunt in Afghanistan, with little help. No more!" Trump wrote on Twitter.
Trump's harsh words drew praise from Pakistan's old foe, India, and neighboring Afghanistan, but long-time ally China defended Pakistan's record of combating "terrorism".
Enjoy the vote and reward!
Thanks
