That's not the real Scott Walker, @realdonaldtrump.
After Wisconsin Gov. Scott Walker hammered Hillary Clinton, the presumptive Democratic nominee for president and Donald Trump's opponent, at the RNC convention on Wednesday, Trump sent a tweet thanking Walker:
One problem: @ScottWalker6 isn't Scott Walker, governor of Wisconsin, who spoke at the Republican National Convention. @ScottWalker6 is Scott Walker, television journalist for WDSU in New Orleans.
One minute later, Donald Trump followed with a tweet thanking the correct Scott Walker, @scottwalker.
TV Scott Walker was a good sport.
Clearly, this has happened before.
