It was Obama's choice whether or not to cooperate with the apparent president-elect. He chose to do so, because that was what was good for the country.Hillary conceded on election night, and Trump was recognized immediately as the president elect.
The outgoing Obama administration prepared everything to hand over to the Trump team, including daily intel breifs and hand off information as to what needed to happen, to encourage a smoth transition and functioning of government.
None of that is happening now.
All to soothe one -stick's damaged ego, while he and his bootlicks try to actively sabotage things to damage in the incoming administrations ability to govern.
It is shameful, and a ty thing to do. Outright un-American, and petty.
Donald piece of Trump was not the president-elect until Jan 6 when Congress counted the electoral college results.
Trump's 2016 margin of victory was narrower than Biden's 2020 win is.
You keep making excuses for Donald piece of Trump when he throws tantrums and is actively harming the country. Transitions should happen regardless of whether a piece of like Trump concedes or not, for the good of the country.
Obama was a better president for having cooperated on the transition.
