Sen. Hillary Clinton decided to end her historic presidential campaign, when Democrats called on her on Wednesday, to quit the race and allow the party to unite behind Sen. Barack Obama.

In a statement yesterday, Clinton Campaign stated that Clinton would “express her support for Senator Obama and party unity” at an event in Washington, D.C. on Friday. She will host an event in Washington, DC, on Friday to thank her supporters and express her support for Obama and Democratic Party. Clinton will urge once-warring Democrats to focus on the general election and defeating Republican presidential candidate John McCain.

"Senator Clinton will be hosting an event in Washington, D.C. on Friday to thank her supporters and express her support for Senator Obama and party unity," the communications director Howard Wolfson said.

Obama clinched the Democratic nomination on Tuesday, but Clinton so far had refused to concede. She wanted to wait before deciding about her future, but in conversations throughout the day Wednesday, her aides said, she was urged to end her pursuit. So, late Wednesday, Clinton camp issued the statement of ending her campaign, but the statement did not say if Clinton would formally end her campaign or suspend activities.
