According to Rigzone, Boehner said that the Republican tax reform effort "is just a bunch of happy talk" and that the border adjustment tax a major priority for Boehner's successor, Speaker Paul Ryan is "deader than a doornail." He said he was more optimistic about tax reform earlier in the year, but "now my odds are 60/40."
Earlier this year, Boehner said he was pessimistic about another congressional Republican priority repealing and replacing former President Barack Obama's Affordable Care Act. Boehner said that while Republicans would fix some problems of Obama's law, repeal and replacement is "not going to happen." He added, "Republicans never ever agree on health care."
On investigations into Russia, Boehner told the Texas forum that "they need to get to the bottom of this" but said Democratic talk of impeachment is the best way to rile up Trump supporters.
Boehner made it clear he's happier now that he's left Capitol Hill."I wake up every day, drink my morning coffee and say, 'Hallelujah, hallelujah, hallelujah,'" he said, according to Rigzone.
