> If everyone can call the president, does it matter if anyone does? It sounds like a koan but isn’t that far from reality. Donald Trump’s personal cellphone number has been making the rounds among Washington reporters, dozens of whom have used it over the past few weeks to score brief interview after brief interview with the leader of the free world about his ongoing war with Iran. A partial list of media organizations that have published “exclusive” or “scoop”-y quotes after hitting up Trump’s iPhone includes leading print publications like the New York Times, TV networks (ABC, NBC, PBS, and CNN), foreign newspapers (the Daily Telegraph and Times of Israel), and no fewer than four outlets with Washington in their names (the Post, Examiner, Reporter, and Free Beacon).

> A comedian pretending to be Sen. Bob Menendez, D-N.J., says he talked on the phone with President Donald Trump earlier this week in an epic recorded prank call during which the president discussed a range of policy topics.

Allegedly he'll pick up the phone even for numbers he doesn't recognise. I guess to convince him you have to make it clear how your idea will increase the glory and honour of Donald J Trump.

In all seriousness i think that combo is better then a senior citizen who can barely be reached by his own advisors and is unclear how much of the situation he actually understands. (with Trump it's either zero, Fox News or 4d chess depending on who you ask, but the answer will always be given with confidence).
