Donald Trump, Hillary Clinton Sweep Northeast Primaries

After resounding victories across the Northeast on Tuesday, both Republican front-runner Donald Trump and Democratic front-runner Hillary Clinton demonstrated that they're ready to turn their focus squarely to the general election.

"I consider myself the presumptive nominee, absolutely," Trump said to CBS News' Major Garrett from his rally at Trump Tower in New York City.

After sweeping all five GOP primaries in Pennsylvania, Connecticut, Maryland, Rhode Island and Delaware, Trump made a convincing argument. Similarly, Clinton won four out of five of the Democratic contests, building upon her nearly insurmountable delegate lead over Bernie Sanders.

Trump on Tuesday night launched into one of his most aggressive attacks to date against Clinton, honing in on her email controversy, citing Sanders' attacks against Clinton, and even charging that Clinton only has support because she is a woman.

"If Hillary Clinton were a man, I don't think she'd get 5 percent of the vote," he declared.

Meanwhile, in Philadelphia, Clinton was ready to return the fire. "Now, the other day, Mr. Trump accused me of playing the, quote, 'woman card,'" she said. "Well, if fighting for women's health care and paid family leave and equal pay is playing the 'woman card,' then deal me in."

She attacked Trump -- not Sanders, her primary opponent -- while promising her Philadelphia supporters to return in July for the Democratic convention "with the most votes and the most pledged delegates." She added, "And we will unify our party to win this election."
