It's been done.

The New Civil Rights Movement, March 18, 2017:

The White House says President Donald Trump ignored German Chancellor Angela Merkel's request for a handshake on Friday because he did not hear it. 

"I do not believe he heard the question," White House Press Secretary Sean Spicer told Der Spiegel, the German news magazine.  

It marks the first time the White House has commented since video of the awkward exchange between Trump and Merkel went viral online. 

Reagan in the News (article):

Although Reagan frequently provided the press with photo opportunities - like the example of the appearance at a military base outlined earlier - he rarely held press conferences where issues could be discussed, because the media would report upon Reagan's inaccuracies. Thus, the administration's focus was clearly upon image and not substance. In fact, one of the most famous images of the 1980s is of a reporter having to yell questions to President Reagan as he was boarding a helicopter, because all other access had been so restricted. Reagan pretended that he couldn't hear the questions and got on the helicopter (Herstgaard 1989).
