— -- Republican presidential nominee Donald Trump is set to propose excluding child care expenses from taxation in a major economic speech today, according to a senior-level campaign source.
In a broad address aimed at rounding out a more robust economic policy, Trump is expected to propose ending the estate tax -- sometimes dubbed the "death tax" -- and reducing taxes across the board, calling the proposal the biggest tax reform since Ronald Reagan's tenure.
Trump will also continue his focus on trade agreements such as NAFTA, as well as reducing regulations, focusing on domestic energy sources and reducing business income taxes to 15 percent.
The speech is slated for 11:30 a.m. in Detroit.
Trump first revealed his economic ideas and tax plan last September during a news conference at Trump Tower. The speech in Detroit will "expand on the plan last fall, delivering a more detailed economic proposal,” the campaign source told ABC News.
Trump is also expected to be joined by some members of his newly established economic advisory panel.
