On Wednesday's broadcast of CNBC's "Squawk on the Street," Federal Reserve Bank of Richmond President and CEO Tom Barkin said that he hasn't seen evidence that inflation has cracked, and that while inflation is moving in a good direction, "it's hard to make the case that we're compellingly headed" to cracking inflation and he's searching for "some comfort that we can get inflation that is being felt by people in the economy on average in the median down to where we'd like it to be."
