Input: Consider Input: Richard Nixon used national security as a basis for his expansion of power. He asserted, for example, that "the inherent power of the President to safeguard the security of the nation" authorized him to order a wiretap without a judge's warrant. Nixon also asserted that "executive privilege" shielded him from all legislative oversight; furthermore, he impounded federal funds (that is to say, he refused to spend money that Congress had appropriated for government programs). In the specific cases aforementioned, however, the Supreme Court ruled against Nixon. This was also because of an ongoing criminal investigation into the Watergate tapes, even though they acknowledged the general need for executive privilege. Since then, Nixon's successors have sometimes asserted that they may act in the interests of national security or that executive privilege shields them from Congressional oversight. Though such claims have in general been more limited than Nixon's, one may still conclude that the presidency's power has been greatly augmented since the eighteenth and nineteenth centuries.

Output: Under what basis did Richard Nixon assert an expansion of the power of the President?

Input: Consider Input: Regular script typefaces are also commonly used, but not as common as Ming or sans-serif typefaces for body text. Regular script typefaces are often used to teach students Chinese characters, and often aim to match the standard forms of the region where they are meant to be used. Most typefaces in the Song dynasty were regular script typefaces which resembled a particular person's handwriting (e.g. the handwriting of Ouyang Xun, Yan Zhenqing, or Liu Gongquan), while most modern regular script typefaces tend toward anonymity and regularity.

Output: What are commonly used?
