Do I fold here in a live tourn

[Vetstadium]

This is a 77 person tourn down to 27 I am BB with AK suited. Blinds are 600-1200 you start tourn with 5k chips no antes. I have 9700 chips and 1200 into BB. Player mid way pushes all in for 8000 (he has pushed at least 5 times preflop so know I am calling him here no brainer it is his only move). The button also calls with 7500 chips new to table just moved and no read. Do I call or wait? I called just seeing your play thanks
