Two sources familiar close to Scott Walker have revealed that he is dropping out of the race to become the Republican nominee for president.

The Wisconsin governor has allegedly planned a news conference Monday evening in Madison, Wis., where sources expect he will make the announcement, and become the second nominee to drop out of the race, according to ABC's Philadelphia associate ABC 6.

Sources revealed this information under the condition of anonymity since they're not authorized to speak before Walker, 47, makes the official announcement, according to the Associated Press.

Walker had tried to make his appeal as a religious conservatives, tea party conservatives and the more traditional GOP base. He labelled himself as "aggressively normal" while campaigning on a Harley-Davidson motorcycle.

Walker sored in the polls shortly before formally announcing his candidacy but has nosedived since Donald Trump, Ben Carson and Carly Fiorina entered the race. Just last week, he annouced he was rebooting his campaign after some early stumbles – namely, failing to reveal his stance on various issues, according to the Chicago Tribune. 

Walker joins former Texas Gov. Rick Perry as two early dropouts of the 2016 race.
