NEW YORK (AP) — The future Republican vice presidential candidate’s plane is currently parked in an undisclosed hangar, an empty spot on its fuselage where a decal featuring his or her name will soon be placed.

Fundraisers have been planned.

All that’s left: an announcement from former President Donald Trump unveiling his pick.

Senior advisers and longtime allies insist they still don’t know whom the presumptive GOP nominee will choose to join him on the ticket — with many believing the choice is still in flux.

The decision will come at an unprecedented time of upheaval in the presidential race. President Joe Biden and the Democratic Party continue to grapple with his dismal debate performance and the intensifying calls for the 81-year-old president to step aside in favor of a younger candidate.

The Democrats’ crisis has given Trump little incentive to change the subject with a VP announcement that would be sure to draw a flurry of attention and focus.

But Trump will have plenty of opportunities this week to ratchet up the speculation about a process that his team has kept extraordinarily close to the vest.

“It could happen anytime this week,” Trump senior adviser Jason Miller said in an appearance on Fox News.

Opportunities to announce

Trump has two rallies planned. The first is scheduled for Tuesday evening at his golf club in Doral, Florida, near Miami. The primetime scheduling and location would seem to provide an ideal opportunity to unveil his pick if it is Florida Sen. Marco Rubio, a Miami native who is one of his top contenders.
