U.S. President Donald Trump's campaign sought to energize women voters in the battleground state of Pennsylvania on Tuesday, betting a message of economic prosperity will boost support from suburban women uneasy with the direction of the Republican Party.

Lara Trump, the president's daughter-in-law, urged the several hundred women gathered at a casino convention center outside Philadelphia to ask their neighbors whether they have more money in their pockets and are paying less taxes since Trump became president.

"The reality is that for a vast majority of Americans the answer is yes," she told supporters — mostly white women — at the event in the King of Prussia suburb.
