Sen. Ron Johnson (R-Wis.) made headlines this week for his heated confrontation with Secretary of State Hillary Clinton on Wednesday during her testimony before the Senate Foreign Relations Committee. Johnson alleged that the Obama administration had "purposefully misled" about the nature of the Benghazi, Libya, terrorist attack on Sept. 11, 2012 that killed Ambassador Chris Stevens and three other Americans.But the 2010 Johnson disapproved of criticizing foreign policy publicly when there are troops in the field.
