President Barack Obama will hold a press conference Wednesday night, the White House announced on Twitter.

Among the Big 4 TV networks, ABC, CBS and NBC will all carry the press conference live at 8/7 CT, while Fox is sticking with a regularly scheduled broadcast of So You Think You Can Dance and directing viewers to its coverage on sister networks Fox News Channel and the Fox Business Network via an on-screen graphic.

Fox adopted the same approach for Obama's April 29 prime-time address to the nation, a decision that came in the wake of the Big 4's increasingly loud grumblings that each presidential interruption costs the networks at least $10 million in lost ad revenue.

Obama's latest TV appearance — his fourth prime-time press conference since taking office in January — comes as his overall approval rating dips below 60 percent (per a Washington Post-ABC poll).
