Trump news: Impeachment case 'to be made by Mueller this week', as president attempts to defend his racism in press conference

Donald Trump's “high crimes and misdemeanours” will be made public when Robert Mueller gives testimony before Congress later this week, says House Judiciary Committee chairman Jerrold Nadler.

Speaking on Fox News Sunday, Mr Nadler said the former FBI special counsel has “substantial evidence” that the president violated the law “six ways from Sunday”, which will be made clear to the American people when Mr Mueller discusses the evidence contained in his 448-page report into the administration before his panel and the House Intelligence Committee on Wednesday.

In a new embarrassment for the administration, US Customs and Border Protection has been forced to admit that no new stretches of Mr Trump's much-promised border wall have actually been built since he took office in January 2017 - all the work ongoing so far has been to repair pre-existing barriers.

Donald Trump said officials in Iran “lie a lot” while refuting Tehran’s insinuations the US did not take down one of its unmanned drones.

“We took down one of their drones. Instead of saying 'yeah that happened,' they lied. They say it didn't happen,” he said. “So there's a lot of proof. It's called, take a look at it on the ocean floor."

Mr Trump meanwhile said on Monday he could win the war in Afghanistan in a week, but that he doesn’t want to kill millions of people and wipe Afghanistan “off the face of the earth.”

The president met with the prime minister of Pakistan at the White House to start the week, while trying to persuade Pakistan to help get a deal with the Taliban that would end America’s longest war.

“I could win that war in a week” but “I don’t want to kill millions of people,” he said.

Afghanistan is high on Mr Trump’s agenda as he meets with Pakistan’s prime minister, Imran Khan. Their testy relationship may be improving. Mr Trump says Pakistan can use its influence with the Taliban to help the US “extricate” from Afghanistan.

Pakistan, which is suffering economically, wants to reset relations with the US in hopes of securing more investment, trade and possibly a restoration of American aid that Mr Trump cut.

Mr Khan said he’s never believed that there was a military solution to the war. He said he thinks the US and the Taliban are closer to a peace deal than ever before.
