Vice President Mike Pence vowed in a tweet Monday the United States would not repeat the mistake of the previous administration when Iranian protestors resisted the regime in Tehran.

As long as @RealDonaldTrump is POTUS and I am VP, the United States of America will not repeat the shameful mistake of our past when others stood by and ignored the heroic resistance of the Iranian people as they fought against their brutal regime... (1/2) — Vice President Mike Pence (@VP) January 1, 2018

Pence also vowed not to let down the demonstrators, although he gave no specifics of a course of action to aid them.

(2/2)...The bold and growing resistance of the Iranian people today gives hope and faith to all who struggle for freedom and against tyranny. We must not and we will not let them down. #IranProtests — Vice President Mike Pence (@VP) January 1, 2018

At the beginning of the protest last week, Pence also tweeted his condemnation of the Iranian government and support for the protests.

.@POTUS & I stand w/ peaceful protestors in Iran who are speaking out for freedom & we condemn the arrests of innocents. The time has come for the regime in Tehran to end terrorist activities, corruption, & their disregard for human rights. #IranProtests https://t.co/PcZMk07RcB — Vice President Mike Pence (@VP) December 30, 2017

Pence's support for the demonstrators comes as President Donald Trump has also sent out several tweets pledging American support for the demonstrators and stressing it is time for change in Iran.
