Welcome to Axis ProRata, a podcast that takes just 10 minutes to get you smarter on the collision of tech business and politics.

I'm Dan Premack. On today's show, Elon Musk just can't help himself in the upcoming IPO battle between Uber and Lyft.

But first, the growing trade crisis between the U.S. and China, which is actually now playing out in Canada.

So you'll probably remember that President Trump and Chinese President Xi Jinping had dinner a little over a week ago in Buenos Aires in order to ease trade tensions and maybe even lay the groundwork for a possible deal.

But at about the same time, a lot of that progress was seemingly blown up as Canadian authorities arrested the chief financial officer of Huawei on allegations that she basically caused several banks to unwittingly violate sanctions on Iran.

So yeah, she's a pretty big deal. Second, the arrest happened in Canada, but it's not really about

extend in today, but the endgame is whether or not she's extradited to the U.S. to stand trial for

fraud. Third, White House Economic Advisor Larry Kudlow told Fox News Sunday that President Trump didn't

know about the arrest until well after it occurred and the dinner plates had already been cleared.

So, per usual, top-notch executive branch communication going on.

And finally, fourth, a lot of U.S. companies are very freaked out. Cisco, for example,

has halted all non-essential personnel from traveling to China for the time being. The bottom line,

this is like throwing a bowl of pudding at what was already a very messy situation.
