The "BC" issue (really, the eligibility issue) was started publicly in the spring of 2008.
Trump reignited the issue in the spring of 2011, causing Soebarkah to release the fraudulent long form bc.
Both, prior to 2012.
My bad on the dates.
Obama have had personal animus toward Trump over the BC issue but it sounds like he was spying on far more people than Trump. Like Cruz as he was a potential nominee. And Mittens in 2012.
And wasn’t it the Hillary campaign in 2018 election who first raised the BC issue?
