question:
Passage: Samuel James "Sam" Ervin Jr. (September 27, 1896April 23, 1985) was an American politician. A Democrat, he served as a U.S. Senator from North Carolina from 1954 to 1974. A native of Morganton, he liked to call himself a "country lawyer," and often told humorous stories in his Southern drawl. During his Senate career, Ervin was a legal defender of the Jim Crow laws and racial segregation, as the South's constitutional expert during the congressional debates on civil rights. Unexpectedly, he became a liberal hero for his support of civil liberties. He is remembered for his work in the investigation committees that brought down Senator Joseph McCarthy in 1954 and especially for his investigation of the Watergate scandal in 1972 that led to the resignation of Richard Nixon.

question:
Passage: In 1795 Fijnje returned to the Netherlands (after the Batavian Revolution), after which he became a member of the commité van waakzaamheid (the Batavian version of the French Committee of Public Safety), chaired the Provisional Representatives of the People of Holland for a while. and - together with Samuel Iperusz Wiselius and professor Theodorus van Kooten - served on the committee for the liquidation of the VOC. In all these posts he took radical viewpoints, but he also enjoyed himself thoroughly. On 22 January 1798, he performed a Coup d'état with general Herman Willem Daendels, Pieter Vreede and Van Langen to guarantee "the unity and indivisibility" of the Batavian republic. The radical and omnipresent Fijnje represented the Uitvoerend Bewind and founded the "Binnenlandse Bataafse Courant" (Interior Batavian Courier). The controversial unitarissen did not long remain in power, for on 12 June 1798 general Daendels led another coup, this time putting the "moderates" in power in the Uitvoerend Bewind. For the corrupt former exiles with explicit opinions, whether democrat or aristocrat, there was no longer any place. Fijnje and Van Langen were locked up until the end of the year in the Gevangenpoort, accused of embezzling state money by the public prosecutor Van Maanen, but never put on trial.
