Donald Trump 'ignores security advice' for the phone he tweets from

Donald Trump has been resisting White House security measures for the mobile he tweets from, officials have claimed.

The US president, a prolific tweeter, has reportedly refused requests from staff to strengthen security measures for the iPhone he uses to send tweets.

The White House's security experts have urged Mr Trump to swap his phone once a month, but he has resisted, telling them it is "too inconvenient", according to officials.

Mr Trump has been using the phone - equipped only with the Twitter app - for the last five months without having it checked by security experts, website Politico reported.

It was also revealed the president uses "burner phones" for phone calls, regularly calling his aides on different phone numbers and sometimes even blocked numbers.

However the iPhone, only capable of making phone calls, is not equipped with sophisticated security features, the officials claimed.

Mr Trump's predecessor Barack Obama is thought to have handed over his White House phones every 30 days to be examined for potential hacking and other suspicious activity.

In contrast to Mr Obama's devices, the phone has a camera and microphone which intelligence officers fear makes it vulnerable to hackers.  

US intelligence agencies have previously highlighted the risk of foreign actors exploiting mobiles to snoop on government officials. 

During the 2016 election, members of the Democratic Party had their emails hacked by Russians, US spy agencies concluded. 

A member of Mr Trump's team told Politico the devices were "more secure than any Obama-era devices" thanks to advances in technology. 

The official added the call-capable phones “are seamlessly swapped out on a regular basis through routine support operations. Because of the security controls of the Twitter phone and the Twitter account, it does not necessitate regular change-out.” ones?”

Meanwhile it was claimed on Tuesday that White House aides deliberately use poor grammar when drafting tweets for Mr Trump to make them look like they have been written by him. 

White House staff capitalise random words, frame tweets with loosely connected ideas and use plenty of exclamation marks to echo the president, sources told the Boston Globe.

Staff-written tweets reportedly go through an informal vetting process whereby Mr Trump is given three or four sample tweets and he picks which one he likes best before it is posted.
