US stock futures inched higher around the flatline as Wall Street braced for July's inflation report and President Trump revealed his pick to head the Bureau of Labor Statistics.

US Stock Market Today: Wall Street's main indexes opened higher on Tuesday after data showed inflation rose broadly in line with expectations in July, putting the Federal Reserve on track to lower interest rates next month.

The inflation data, which is prepared and published by the Bureau of Labor Statistics (BLS), is bound to be the day's biggest market-mover. The authenticity of the results themselves will also be a topic of serious consideration, in part because of the controversy surrounding the agency in recent weeks.
